Did you package it according to the instructions, including the3 return slip with the RMA number inside of the box with the device?  Do you have confirmation it was delivered?  Have you contacted the shipping company to verify it was delivered if T-Mobile says they have not received it?  

 I'll spread the word on social media to warn others that t mobile must be doing so bad they are scamming their customers! This is criminal.

will you be putting in as much effort to point out that all the carriers run into this or are you mainly saying this only happens with TMO?
