I was a T-mobile customer for 9 years and I got screwed over big time. I was charged $400 for a phone that did not have any physical damage, I just had issues with missing messages. Don't know where they went but people would send me messages and I would not get them. The guy who inspected my phone at T-mobile said that my phone was under warranty and that I only had to pay a $5 processing fee. After a month, I received a letter saying that I need to pay $400 because my charger port was messed up (Totally unrelated to my problem). I called customer service to get this fixed because it was not fair that they send me this letter when I was told, with proof, papers stating that I will not pay anything except $5 for the warranty exchange processing. When I called customer service, nobody was really willing to listen to my problem and kept saying "we cannot do anything about it, you will have to pay the 400" ... If I knew that I had to pay $400, I would have never sent my phone (which wasn't completely defective, I just had trouble with messaging). I don't even believe my charger port was damaged because I never had problems charging, but for them to charge me 400 for that is just ridiculous. I could have bought a new phone. My bill for this month was $660. This company is just horrible. And I wish they would hire people with more experience and customer service skills.
