I Hate T-Mobile →[More:]I'm canceling my T-Mobile account because of their customer service. I've been with them for over two years, and recently missed a payment for the first time. They included the missed payment on the next bill, which was fine, but then they started harassing me.

First, they text-messaged me demanding payment. That was on a Friday, after I had already gotten the bill and scheduled a payment for the full amount due. The following Monday, a customer service rep called me and demanded to know when I'd be paying the bill. He wanted me to pay the late amount immediately, but he had to settle for me telling him I'd already scheduled a payment on the due date, and he "made a note" that I'd be paying. (I told him that I didn't appreciate being hassled over a first-time missed payment.) Then a couple days later I got a letter saying they were going to cut off my service if I didn't pay immediately. Again, this is after one missed payment after several years of paying on time.

I have to confess that I called their customer service to yell and swear at them as soon as I got the letter. (They'll hang up on you if you swear three times, so prepare your swears in advance.)

When I called again a few days later to see if my contact had expired and tell them I was planning on canceling my service because of their harassment, they said I had an excellent payment history.
