Query: phone is mediocre but t-mobile is the worst

My phone broke after a month or so. After spending 30 minutes on the phone during which time t-mobile continually wanted to blame me (did you put it in fluorescent light, did you put it in the sun, did you drop it, did you put it in your pocket and bend it, did you put it in your pocket and bump into something, did you drop it, did you break it, did you do something bad to it) they finally relented and agreed to send a new one with the oft repeated comment that if they determined that the phone was damaged then they would charge me untold sums of money.The most amusing part of the conversation went like this: would you like UPS ground which will take 10 days or UPS 3 day which will cost $15? When I responded that the ground would be fine she said "OK, that will be $9.95". I had to laugh at their arrogance.
