Shoutout to Simon for the great customer service. Very helpful with all the information he was able to provide to my husband and I. Thank you for helping us redeem our picnic blanket as well. read more

The staff here are truly the best! We were just visiting the area, as we took our Family to eat at the Rainforest Cafe, coming all the way from Duarte, and we didn't really have any intention of stopping in... but I'm so glad we did. I had a couple of questions about phones and promotions, and Sanjay answered them very quickly. Although they were about to close, they didn't rush us out at all, but both he and Bri went above and beyond to assist us! I was really blown away by the service because let's be honest, it's not common these days. With these two as employees, your store will surely succeed!!! Sanjay and Bri 10/10 read more

Lance the sale man is a fraud. This whole company lacks integrity. We upgraded our phones due to 2 years passing and the phones not working as original. Somehow in this process someone changed our service plan. Our bill increased from $186 to $236 a month despite Lance telling us it should be $186. Nobody will fix it so we are going to Verizon (a real company instead of a knock off company). We will be consulting the BBB as well. Avoid T Mobile unless you plan to get lied to and screwed over. read more

Sanjay is very professional and will make sure the customer leaves with in utmost satisfactory way. He had so far helped us couple of times now and every time we have been well informed about everything. Just for Sanjay 5 stars. read more

Yeah I went here last night to pay a phone bill and the guy was very rude music was blasting loud i couldn't get his name felt like I was being rushed out the store but he was a heavy wight guy Just was very rude read more

JOE WAS ABSOLUTELY AWFUL! I mean wow! His attitude, laziness, and unwillingness to help me or his coworker Jonathon was pitiful. He sat there on his phone the entire time, side-eyeing Jonathon anytime he asked a question when trying to help me. I felt so bad for Jonathon...he was so kind to not only me, but to "Joe" who was so disrespectful to him. Absolutely disgusting. This man also said (word for word) that I am "full of s***" under his breath, but I was still able to hear clearly and acknowledge. I responded when leaving and said I don't appreciate his curse words, called him out for being lazy, and thanked Jonathon for his help. Check the cameras, the proof is there. This was on 03/31/25 at around 7:30 PM. He should be fired for his laziness, bad attitude, and trying to intimidate people with his corny mean mug, and Jonathon should be promoted for his kindness, helpfulness, and sweet smile! God bless you Joe, Jesus loves you! read more

I always have a great experience when I go in and talk to the customer service and the people in the store they always know how to get me the best deals at the best service that's why I've been with them for 19 years read more

very unprofessional blasting loud rap music. and talking to the point where I have to wait ten minutes for them to finish their conversation once they do they start laughing loud and finally help. DO NOT COME HERE THESE GUYS ARE NOT MINDFUL AND NOT DEMURE read more

lazy people working there tonight 8/9/2024 And just wants to get off from work. Very bad customer service, not helping customers to solve the phone problems. I have 5 lines with T-Mobile and I don't deserve this kind of service. This lazy bone dropped my sims card twice on the floor. How professional he was!! read more

My parents are looking to transfer to Tmobile and followed them to make sure they are being taken care of. And the moment I stepped in my dad was telling me how he liked the girl assisting them. Even my mom was so happy with service. It's rare for them to really get satisfied with service that would ask me to post a review because of Hiltinnie. She is energetic with a fun personality that is contagious. She helped my parents with the process and answered all questions (btw my parents have a tendencies to ask a LOT of questions) with a welcoming response and even accommodated my dad's joke even when they're nonsense. Never once had we felt that we are a nuisance. I usually steps in to help my parents. But this time I'm just glad to see how they are being taken care of by Hiltinnie. If you need an efficient, quick service I would definitely recommend her. read more

While I did experience a good first impression on this place with their employees and quick customer service, I'm more upset that the employee who was assisting me didn't tell me about the promotion that was going on. I've had the same iPhone 5s, yes iPhone 5s for the past 5 years (my phone was in perfect condition, it is the perfect size for me to stick in my jeans back pocket, and battery life was amazing and lasted all day-- so why should I have upgraded??). I walked in just curious to see how much an iPhone 8 was. Clearly I am interested in the iPhone 8 but he didn't tell me there was a BOGO deal on it! When I called just a few minutes ago, they stated they previously had a BOGO deal for the iPhone 8 for the past 3 months, but it ended just last week!! How am I supposed to know about these promotions if I don't see any ads, or especially when I walk in interested to purchase the iPhone 8 and you don't tell me about it!! If he would've been helpful, my boyfriend and I would've gotten the BOGO deal right then and there. read more

The customer service is horrible! They even don't want to let you finish your question and hang up directly!

I've been having issues with my phone a Galaxy Note 10 plus for a month. I've spent countless hours on the phone with agents and specialist. It was even suggested I change my plan. I took it into T-Mobile in the Ontario Mills mall and Rosie T. fixed it. I am so impressed with her knowledge and tenacity. She provided individualized care and provided her undivided attention. Thank you Rosie read more

Unlike the their reviewer, my first impression was not as pleasant. I came into the store with my previously unlocked T-Mobile iPhone, and inquired as to why it was no longer unlocked, since I tried using on other carriers. The associate that helped me was not pleasant about it, and gave me a number to call, of which also did not want to help. But luckily, my second visit a few days later, Hiltinnie had me in and out in under 15 minutes with a new prepaid line, and she also waived the SIM card fee, and activation fee for me! Talk about customer service, and all the while with a smile. She'll gladly help you out! read more

Johann Velazquez's Truck team at the LA County Fair are total life savers. Super friendly! Go by and see them for all your t-mobile needs!

Great customer service. Jhon was my rep and did a great job of informing us, as we were switching from a very long stint with another carrier. He was patient with plan selection, phone choices, trade in options, sign up, app tools and ordering a phone color that was out of stock. Highly recommend a visit here. Glad we made the switch read more

Sanjay and Jhon were amazing to help me out with my situation but the customer service back in April 2022 that I asked to cancel my line kept charging me for an extra line that I had cancelled so for the past 9 months I've been paying $60 a month and all they could give me $120 back instead of $540. T-mobile has been cheating me out of my money. The only reason I'm staying in T-Mobile is because of Sanjay and Jhon. read more

I am surprised myself that I am writing a review for t-mobile. Because most of my reviews are for restaurants. However, this location inside Ontario Mills has to be the best t-mobile I've visited. Just happen to run into this store by chance. My mom is shopping and her phone wasn't working. I hate shopping, so I took her phone to try to fix it. Basically, the phone has full bars but it is not able to call out or receive phone calls, data service however, is working perfectly, weird problem. I looked up t-mobile Ontario Mills directory and off I went. I met Anna, who was very friendly and helpful and ran through all the possibilities that could be wrong with the phone. Make the long story short, the problem was fixed in the end and my mom was a happy camper when I gave the phone back to her. Great store, will visit again for sure. read more

I had canceled my Services with T Mobile after Tina of dropped calls and bad service in general. We had a business account and had paid it in full upon leaving. They had our phones locked and wouldn't help unlock our phones when after several trips into the store. They keep telling me that they weren't locked anymore and charged me to unlock them online. Still months later we were then sent to collections when we have not even had there Services for 6 months. They had generated bills that we never got because we no longer had accounts with them. After 100 of hours in the phone with their international customers service reps they still failed to get rid of the bills. Even to this day they say we owe them one penny even though we actually paid a penny just to shut them up. Unbelievably poor customer service so the way around and corrupt and thievery practices that probably get thousands to just pay them to stop collections. I will find a way to file a class action law suit against them. They must do this to all of there old accounts. Stay extremely clear of what was Sprint/ T-Mobile. read more

liars liars liars!!!! avoid going here lied to me added accounts with my consent tell you one thing before opening an account and you get the bill and is not what they promised you read more

I Been a Tmobile customer for the past 10 years, I'm Very happy with the service and I have always been treated great, till yesterday I went to this location and I was treated very bad by a guy named DANIEL, I think he's having a bad day or something. I asked him a question about an account I'm an authorized user on it he responded to me like I'm dumb or something, and he slammed the iPad back towards me and he's like idk what you're talking about, well isn't your job to make things clear to me about my account, like idk what he think he is, can someone tell him he works at Tmobile and he doesn't own it, and on my way out I was still respectful and i appreciated his help and he refused to respond back, shitty customer service he got. read more

I have been with T-Mobile for years and always had great service. I came into this store expecting the same, but was even more surprised by how much better it is actually working with someone face to face. I believe the person helping me was named Rose? She was extremely informative on the new programs and even went out of her way to check to see if there were any new plans that would fit my lifestyle better. I really appreciated how she made me feel like a welcomed customer. I will definitely be back to purchase a Note 10 once I can convince myself I need a new phone. read more

This is the 3rd tmobile I visited trying to replace my screen protector since the other stores were sold out. Rose immediately told me that they were out but she would be happy to ship it to my house (something that the other stores NEVER offered me). I got it yesterday and a went to my local T-Mobile to get it installed. I don't know why other stores never offered me this option or even cared to help me. She took my information and address and in under 5 minutes she was done.Thank you Rose. read more

Just came in to make a payment, never had such a great experience. Ana greeted and helped us right away. She asked us if we were happy with our service and if there was anything else she could do for us. While we paid she was personal and just seemed like she had a great heart. She even asked us if we had out tmobile tuesday app. Yes girl we do! What is usually an uneventful trip to pay turned into leaving a little more energized and happy. Thank you Ana! read more

Sonia was very helpful and funny and got us in and out. Store wasn't to busy until we came back later in the day. Thank you again Sonia you're awesome read more

HORRIBLE EXPERIENCE THANX TO ONE OF THE GIRLS WHO WORKS THERE!!!!!! My girlfriend wanted to get an iPad so we went here & Hiltinnie (I think is how it's spelled) helps us, now at first she seems awfully jumpy & shaky to the point we thought she was on drugs or waay too many energy drinks, then later we thought maybe she just has a problem of some sort. We tell her what iPad we want, she's going over it all with us, telling us how much it'll be a month, how much down, then if we change the billing to auto pay... Now all this she's writing on a paper so she can show us, we go with the better iPad and she puts all the paperwork in, has to do the "phonecall" part, after all that is done my girl signs the paperwork & we leave. 3 days later she checked on the iPad cause they have to ship it, it was the WRONG IPAD!!!!!! Now we have to pay to send it back, restock it, for the billing cycle it's on & to get the one we did want we had to pay everything again. It was her mess up not ours HERS, why do we get screwed over? read more

I came here last Tuesday and was helped by Zulena and by far it was the best purchase experience I've ever had at a T-Mobile in my history as their customer. With me, customer service goes a long way and she absolutely gets it. She is welcoming, friendly, and patient - she does not at all mind having to explain things to you more than once. I ended up returning a phone to get an iPhone and then some so it took a while but I was happy to be helped and to get exactly what I wanted. Thanks, Zulena!! read more

This is my favorite T-mobile store. There is another in the mall that was a sprint previously. Stay away from that one

Daniel helped me with my voicemail not working on my dads unlocked Samsung S7. My dad is 77 years old and Daniel was patient and helpful with answering all my dads questions. I kinda felt bad because I'm not as patient as Daniel. Or as my mom called him Da Niel . Overall I will probably come in this weekend to see their promotion on TmobileTv and whenever Tmobile gives gifts for Tmobile Tuesday we make sure to stop in and say hi to the Daniel. read more

If I can give this store a 0 no I would, every TMobile store I've been to have great customer service and help me out in every best way they can. I'm not a person to believe reviews but I understand know why they have bad reviess online (Google). The associate PAULA was so rud and helpless on the phone I called to check on something that said clearly in stock online first thing she said was NO didn't bother to explain the process or how it works so I asked "so I'm on TMobile app online and it's saying a few location who have them in stock, ur saying it's a lie and she said YES" THATS HORRIBLE customer service and I asked for her name and saying all be calling ur manager about you she said okay Instead of trying to fix the situation she clearly didn't care so I called another TMobile store we're I was greatly appreciated and explained the process and asked if there's anything else they can help me. Then the Manager calls me back but I didn't give them my number or asked for him to call me back that's harassment and unexpectable and I would never go to this store or wish noone to go to this store... clearly PAULA needs to learn how to work customer service and help customer out in every was they can read more
