T-Mobile Sucks!!! I was with AT&T and was promised a ETF reimbursement however, I switched any way because of their family plan and my bill would be much cheaper. After being on TMobiles network I rather pay for the more expensive service because it makes my phone run better. I switched on February 2,2015. My ETF wasn't approved until 3/28/15. As of today I still havent received my ETF Card , and my final bill was due on March 25,2015. Fooling with Tmobile they will have you in collections before you receive the CARD.. If i would have know this I would have never switched services!!! DO NOT SWITCH PEOPLE..!!!
