    This review is for T-Mobile employee Samantha A…read more My wife and i went to T-Mobile last minute to go preorder some iPhones. We didn't realize how busy it would be but quickly found out we may not be able to preorder our phones and also grab lunch before we both had to get back to work. After waiting awhile we got called on by Samantha. We asked her how long it would take to preorder phones and also combine our plans. She said 15 minutes. To be honest I was really skeptical bc I feel like most trips I had to ATT and Verizon would take minimum 30 minutes. Once we got going I totally forgot about the timing. She was hustling but didn't make us feel rushed. She was friendly, attentive and knew all the steps of the process. This is the first time I felt truly valued as a customer when visiting a mobile provider. After we finished the final step she said 15 mins and 9 seconds. Coming from Verizon who has horrible service and even worse customer service, this was a total pleasure and all thanks to Samantha. We felt fortunate we got assisted by her bc otherwise we would have likely missed our lunch and we felt truly valued. Sorry it took so long to leave the review. We wish you the best and hope you have a great rest of 2023. Get this woman a raise or bonus - something. Exceptional talent and amazing human being. Thanks again.

I contacted Ricardo after checking out his reviews, he responded quickly and we easily set up an appointment. He discussed possible options of placement of the ports since the roof and outer walling might pose an issue, but he was able to find good placement of my ports. Job was done quick and easy in less than 2 hours. Aside from making a hole in the wall for the ethernet port placement, no additional breakage of the wall was necessary. Ricardo did say that in some cases, depending on the walling and roofs, breakage of the wall would be necessary for some people, but not mine fortunately. Ricardo and is colleague were awesome, professional yet friendly and personable. They cleaned up after themselves and did an overall fantastic job to make any streaks or scrapes anywhere. HIGHLY recommended if you are looking to have ethernet ports installed that extend from your main router/modem that go through the wall/roof so you don't have ethernet cords lying around on the floor.

    My husband and I were ecstatic when we found out that our apartment community was serviced by…read moreVerizon Fios - our first thought was YES fast internet and hundreds of channels!! Then just 5 months later to our dismay a company called Frontier was taking over. Since the transition, we couldn't get ahold of ANYONE! We couldn't get ahold of customer service, tech support or even get a real human being on the line to pay our bill!! I loved Verizon because of the OnDemand program - I could come home after a long work week and catch up on all of my favorite shows. But after the transition, everything was deleted and it would be months before they would upload each show or each network. Then three days ago, our cable completely went out! The error read "please check the coax cable connection between the RF In and Fios TV IN of your set top box and router." After doing this, securing all cables and rebooting the cable boxes about 10 times I called their customer service line. I was on the phone with a representative for over an hour trying to troubleshoot my cable when she finally said they would have to send a tech out in 2 days. The tech would arrive between 9AM and 5PM - what kind of time frame is that? There goes my entire day off. So today, we made zero plans and waited for a phone call or knock at the door. The tech never arrived and our cable is still out. I cannot wait to cancel my service with Frontier TOMORROW! This has been by far the worst in cable and internet service and would not recommend them to anyone!!!

    Frontier is absolutely horrible... a complete joke. It's frustrating when you sign up for quality…read moreservices (tv,intern, phone) and get switched over to horrible qualify. No HD, NO ACCESS TO ON-DEMAND, RIDICULOUS WIFI SERVICE since April. I've been complaining for a whole month, had a tech scheduled..... never showed up.... THANKS FRONTIER FOR WASTING MY SATURDAY.... THE ONLY DAY I HAVE OFF!!!! Fyi: if your gonna missed a scheduled appointment it's great customer service to call and let them know. If you haven't been able to fix your issues for a month at least allows customers to get out of contract. I was on hold for over 3hrs, everyone i spoke to didn't know anything couldn't get ahold of tech couldn't tell me an ETA...I can't believe you guys don't have it together how can you expect customers to wait from 8am - 9pm without giving them an estimated time or a smaller time frame. Completely dissatisfied, disappointed, and i will never recommend to anyone!
