The tech comes to my new address and is in such a rush, he leave the fiber optic cable dangling on the floor in the basement. Additionally I give home three cable boxes and a modem from my old address. Low and behold Optimum is now trying to charge me for 3 cable boxes and a modem. Fast/slow forward 2 weeks, miraculously they found the modem but not the cable boxes. The charge went down from $700 and change to $500 and change. It is absurd that they now, still want to charge me for their incompetent tech mishandling of the equipment. The company is one huge scam. There product is subpar as I'd their customers service. My next email and call will be to the BBB, and my state reps office. Do yourself a favor and find another provider for your cable, internet and phone service. BEWARE!!!!!

A couple of months ago, I had an amazing experience at the T-Mobile store in Stamford Town Center…read more My phone had broken right when I was in the middle of moving, and all my things --cards, documents, everything-- were packed in boxes. I was very nervous and stressed, but the team was extremely kind, patient, and professional. The manager and the whole team treated me with so much empathy that they managed to calm me down after almost four hours of stress. Through their kindness and sense of humor, they made me feel truly cared for. It wasn't just a simple thing they did -- they really made a difference on a very chaotic day for me. Every time I see my phone, I remember with gratitude everything they did to help me. I definitely recommend this location and would be very happy to return. Thank you from the bottom of my heart for your amazing service and for showing that there are still people who truly care about their customers.

However, as of 3 months ago, it has been one nightmare after another with Frontier. I have spent over 20 hours on the phone between a service issue in early July ( that was ultimately fixed after much complaining over 3 days that resulted in all kinds of billing issues that I have yet to get Frontier to fully correct. Every time I talk to someone, they say they will get it corrected but the credits need a supervisor and manager approval to correct problem they caused. It took 2 months to get a credit, but then they erroneously charged me an install charge that doubled my bill. I am still fighting with them and feel beyond upset. Their systems don't talk well to one another, their processes make it hard to give credits where they are due and many of their employees lack knowledge of how their systems will bill or how changes they make affects your service & billing. I recently found out that a " retention representative " that I talked to in early July to lower my charges, unknowingly changed some coding in the system that not only caused me to lose my internet service the next day, but completely changed my service plan and doubled my billing erroneously!!! So, instead of saving me money, I lost service and have spent hours and hours on the phone for months before I was able to talk to a knowledgeable person who cared enough to help me & explain the problem. We are not done correcting the problem yet, but progress has finally been made. It's been a nightmare experience that I would not wish on anyone. It's really quite scary that it's so difficult to get to a live person, who is knowledgeable and cares. It seems that the company puts measures in place that make it extremely challenging to address issues with a manager & actually get a call back.
