T-Mobile Internet - $200 Pre-Paid Mastercard - STILL WAITING

I have been in tears with this company for 8 months now. Never got my AAA and my $200 card, two days ago I was told my rebate was void because I activated the box either over the internet or phone. I asked how else could it be activated....no answer. Asked for a supervisor and was told numerous times they were busy. Told the guy I had already been on the phone with them over and a half and that I would wait. Finally he tells me that the gentleman from the store that did my activation would be calling me. I doubted him but he reassured me he would be calling. Still no call. I am actually on my way into the store to cancel my plan. I can't log into my account or anything from my phone. Tmobile gave me a monthly price that was a lie from the start, is no where close to my quote. Then their customer service lying to me put me over the top. The ASS service is what led me to switch and they can't even get that right but they sure can pull the money out of my account with no difficulties. Amazing!!! I'm done and will be co tasting the BBB.  Don't lie to me!! I rather you think me ignorant than straight up lie!
