    My current injuries keep me from using my tablet comfortably so I reached out to Joe for an Apple Pencil. Joe went out of his way to find the one I needed for my model iPad. What's even better is the price I was able to purchase it for! Just to put this out there! It's not just a business... Joe offers a lot of great advice and the environment he has created is absolutely amazing! If you ever need your electronics repaired or are looking for a certain electronic device then Joe is your go to MadScienTech!

    Joe is Legit! If you need any of your devices repaired, he's the man for it! Very patient, fast, and knowledgeable. Needed a whole front screen and back glass replacement for my XS Max and he was able to repair both, initially I went for just the back glass repair, and last minute decided I wanted my front screen replaced as well and he was able to do it same day, leaving my phone looking like a brand new phone! Very please with him and his great customer service! I definitely recommend him, he won't disappoint!

    Phone Repair: Cracked Screen and Water Damage
    Daniel R.

    As a real estate professional my phone is my lifeline. After sustaining water damage and a cracked screen I needed a quick resolution. I contacted Joe last minute and he immediately followed up and saved my phone and my business. Rather than having to wait until the next business day to buy a new phone. He opened up his business late at night and repaired everything within an hour. I highly recommended Joe and his services. He earned my business for life!

    Amazing work with affordable price. Very responsive to your questions and quotes. Very happy with the service. Would recommend Joe.

    If only you could see how many places I asked to quote me... Mad ScienTech was the least expensive by far! He was amazing in speed of responding, and making sure he had the right parts, and finished the phones same day! He was thorough in making sure the phones were running and beautiful; I also appreciated how he was concerned in my front screen being cracked as well. I am so happy with the end result of both phones, and as much as I hope I don't crack the glass of a phone again, I know where to go if I do! Thank you so much again Joseph!

    Fixed iPhone from Mad ScienTech!

    Shop was a little hard to find since it is located in the OSC Motorsports dealership. They are located all the way in the back. There, I met the founder, Joe. He helped me diagnose my iPhone 11 Pro Max problem since it had unresponsive touch. Problem was fixed within 30 minutes! Super professional service and definitely has my business for upcoming repairs!

After moving in I was contacted by Ralph but I wasn't sure I wanted wifi at the time. After a month of settling in, I reached out to Ralph and inquired about their deals and packages. I spent over an hour on the phone with him and he made promises that influenced me to sign up. Those promises include $50 monthly for wifi internet, free installation, $300 in giftcards after 90 days of service as well as first month free if I enroll in auto pay. I signed up towards the end of December and before I knew it, I was already getting a bill in January that was over the agreed $50 even though I enrolled in autopay. I called back Ralph immediately and told him the issue. He told me additional charges from the bill was a wifi security charge then directed me to call a number to get that removed. I followed directions and called the number and they told me it wasn't a security charge but rather for the additional days in December that I had wifi before their cut off point for their bill cycle. I then circled back to Ralph to follow up with him promising $100 of credit because I didn't receive my first month free as promised. I contacted him for over a week with no replies. I got in touch with someone from his building and they confirmed he was in the office all week so should have gotten back. Needless to say, he was hiding so I ended up working with Tony. Tony wasn't all that better. For someone who has been working in the field for so long apparently, his communication was seriously concerning. He promised to get back to me on a definite day and didn't. When I reminded him, he emailed me stating things I already told him I knew and ignored questions I was asking confirmation about. He tried to delay the vouchers and I expressed to him that I have concerns when its time to claim my $300 rewards based on the issues I was already experiencing at the moment. I asked for the $100 vouchers Ralph promised to be an immediate credit and Tony said that couldn't be done which was a lie. I called customer service and made a complaint and the person over the phone immediately credit me the $100 that Tony said they absolutely couldn't do. The story doesn't end there though. It's been 3 months and now its time to collect my $300 rewards. I gave Tony another try and reached out to him. He reminded me to keep an eye out for an email. Once I received that email, I followed directions to claim my rewards. It does say it'll take up to 30 days to receive, but I got notification that it was sent out on 4/8. Today is 4/28 and I havent received it. I checked in with Tony and asked him to look into it to ensure there wasn't an issue and that its on its way. 3 days and no reply from him. I am fine waiting the 30 days as long as we know its actually on its way. I really don't want to wait longer only to find out it was never on its way and have to do the whole process again. Like I said, I shared concerns that there will be difficulty claiming my rewards and sure enough, Tony's lack of communication once again confirms it. I guess I have to make another complaint so the right thing gets done. It's a big inconvenience, but my pet peeve is when people/companies owe me money and go quiet when it's time to collect. I would steer clear of this company and any reps that behave like these two.

About 1 year ago I went into this store on Euclid and Philadelphia in Ontario and was greeted by one of the employees. I stated that I am a loyal customer of 12 yrs and I would like to bring on 3 new phone numbers to Metro (my wife and two teenage boys) and of course they were happy to hear that. This is when I bought 3 new phones and activated service for them and walked out of the store happily. Only to have my wife explain that her phone was not working ie: not receiving all texts and phone calls, apps staying on and music randomly playing at 1am when the phone hasn't been touched in several hours amongst other issues. I brought this to the attention of Metro customer service (in November when I was notified by my wife) at which time they instructed me that the phone has a 1yr warranty with the manufacturer and the Assurant insurance was still valid, so they would process a claim on my behalf. I left the store only to get home 25mins later and received a call from this franchise rep and she stated my phone has been refurbished (not true) and they couldn't continue the claim due to this. At which point I called customer service back and they informed me that I should try the 1yr manufacturer warranty with Samsung, called Samsung and they stated they would need my phone for more than 21 days before I could receive a new one (unacceptable). As this was not an option for me and my family I called Metro PCS customer service back. They in formed me I should go back into the store and have them try to process another claim, at this time the representative from the store I bought the phone at informed me that the phone isn't a Metro PCS device, hmm 1st refurbished and now not a Metro PCS device. I have followed up on this consistent problem for 7 months now only to get the run around from all sides pointing the finger at each other like they are the ones to resolve it. I have spent 50+ HOURS on the phone with customer service and have wasted time and gas going back and forth to this store location, have asked several times to have a manager from this location to call me back to resolve this issue and nobody ever calls me to assist. I have been BEYOND PATIENT with this store and it has gotten me nowhere, here we are at the 1 year marker and have been paying for a service that I have not received from day one. I have nowhere left to go with this as the corporation, the franchise and the insurance company are all useless and refuse to communicate to each other to help me figure out a solution. So this is what's going to happen going forward. #1- I will be reporting them to the FEDERAL COMMUNICATION COMMISSION (FCC). #2- I will be serving the corp with a small claims case and obtaining council to recoup the financial burden this has cost me. #3- I will be giving my hard earned money for 4 phone lines to their competitors #4- I will be sending emails and physical letters to their PO box at the corporate headquarters in Dallas TX #5- leaving as many negative reviews on all platforms including all social media platforms Mind you all of this could have been avoided by just taking care of the customer. Or at least communicating with a loyal customer. Damn you Metro PCS you have caused me nothing but grief for the last 12 months

    Subject: Formal Complaint - Billing Misrepresentation and Unethical Sales Practices at T-Mobile…read more(Holt & Euclid Location) I am writing to formally report a concerning experience involving misleading billing practices and potential exploitation of my friend at the T-Mobile store located at Holt and Euclid. My friend recently visited this location due to issues with her phone and, out of necessity, purchased a new device (iPhone 16). During this transaction, she was not clearly informed of the full financial implications of her purchase and left the store with a significantly higher monthly bill than expected. Previously, she was paying approximately $70 per month. After her visit, her bill increased to over $100 per month without a clear or transparent explanation. When we returned to the store for clarification, we spoke with an employee (name believed to be Adriana or similar) and later the store manager, Victor. During this interaction, explanations provided were inconsistent, unclear, and at times contradictory. Despite repeated requests for a simple breakdown, the information given did not logically align with the actual costs. Here are the key concerns: * My friend traded in her iPhone 13 for a $630 credit toward an iPhone 16 priced at approximately $730, leaving a $100 difference. * Instead of allowing her to pay this $100 balance upfront, she was placed into a financing structure without clear consent or understanding. * She was enrolled in additional features (such as streaming services and add-ons described as "free"). * Most concerning, she was initially charged for a second line that she did not request or authorize, which significantly inflated her monthly cost. * Only after we challenged the charges was this second line removed, reducing her bill to approximately $87/month--still higher than expected based on the actual breakdown of services. Based on the actual numbers: * $55 base plan * $10 protection plan * ~$4/month device balance The expected total should have been approximately $69/month before taxes--not over $100. Additionally, during this interaction, I was labeled as "aggressive" by the store manager when I was simply asking for a clear and accurate explanation. This response felt dismissive and inappropriate, particularly given that we were attempting to understand a situation where my friend was clearly being overcharged. This experience raises serious concerns about: * Lack of transparency in pricing * Enrollment in unauthorized services * Misrepresentation of promotional offers * Pressure-based sales tactics targeting vulnerable customers We later visited a Verizon location, where the pricing and terms were clearly explained, further confirming that the T-Mobile transaction lacked transparency. She is locked in for two years. This situation reflects not just a billing issue, but a broader concern regarding ethical sales practices and customer treatment.

    T-Mobile is a business of liars who are money hungry in these hard times for people…read more They tell you to do things and then they don't follow through with what they told you and act like you're not an intelligent person.

Her name is VERENICE !!! She has been simply amazing , from the moment I had issues with my older unit she did all that she could to obtain a simple trade for me through my insurance of course,. She detected the problem with my unit was a software malfunction, and this made it possible for me to obtain an exchange for my deflected phone . They did not have my model anymore , it had been discontinued, instead they sent me a newer model, which I was happy with , only paid literally 5 dollars for the exchange application fee , I guess you can call it. I still wanted to get their newest android phone model the Samsung S 26 ULTRA , and Verenice said keep the one you have for a few months see how you like it and if you feel that you still want to upgrade do it ! All I could say to that was of course, n I promised her I would come back with her personally in order for her to get the credit from such sale. I finally did come back and had mine and my girlfriend's phone upgraded to the same S26 ULTRA . By upgrading my plan from a senior or dinosaur one ( been with them for like 24 years) she was able to get me a promotion where by trading out phones for the new ones we were able to qualify for the full credit of the cost of both phones, basically 1300 each . And we would have to be responsible for would be the cost of the new plan, or the two lines and the insurance fee. Once I hlt my new phone mailed ,which she patiently helped place the order thru the tmobile app, I came in and had everything transfered into my new unit. She took the time to explain lots of things I needed to know about my new phone and plan and here I am . Saying thank you Verenice for such an amazing and professional help you offered to me ! You are simply wonderful! A great professional and your bedside manners are second to know m I sincerely hope that Chris the store manager realizes what a tremendous asset she is to the store itself and to the company as well. All the knowledge she possess just make you feel safe or secured about making changes like the ones I did. I tried to go back into store and personally give kudos to Verenice and a great report to her manager Chris , but our schedules never agreed . On top of that this beautiful young lady is also Bilingual. Habla Español, and I wa sable to witness also her Spanish skills ar work ! And the patience she used with some really hard and emailing customers ,she had to deal with. How she kept her composure and displayed a flawless act of professionalism with them , was just simply admirable to me. Feel so blessed to have come across you Verenice , thank you for all of your help! Please know how much I sincerely appreciate your service , period !!!keep up the Amazing work ! Look and also for her next time you visit her store ! You will understand better what I am sharing with you . ! Muchas gracias Verenice ! Eres única!
