I had T-Mobile 2002-2004, and I had an extraordinary large number of dropped calls. I let my contract run out, then disconnected by service.
I ended up getting 3 "final" bills. I paid each one. When I got the third "final bill", I called customer service and complained. Customer service was very nice on the phone, and she assured me that this would be the last final bill.
A month later, I got another "final bill" for $30. I was so mad that I did not pay this one.
I never heard another word from them until 3 years later I was turned over to a collection agency. Now the bill is $300 because of interest.
Review about: Tmobile Phone Service.
Monetary Loss: $300.
