Why I HATE T-Mobile!!!!!

I HATE T-MOBILE!!!!!
I purchased a phone with them in December of 2006, as a Christmas gift for my brother. The salesman LIED to me to make the sale! He told me that as soon as my brother turned 18, we would be able to transfer it into his name with no problems, and no credit check. I have been trying to get it switched over to my brothers name for almost year and a half! Every time we call them to do it, the "customer service" people tell me one thing, and tell my brother another thing. They keep giving me the run around. They said they don't transfer services without a credit check. I went back to the original salesman, and he blew me off!
I inquired about a different type of plan which would eliminate the hassle of the credit check. They said I could do a special plan, and even told me what to tell my brother to say when he called. When he did call, they told him that that was not something they did, and he still wasn't able to transfer the service to his name.
I would like to cancel my service with them, and they want to charge me the full cancellation fee, despite how many times they have lied to my in the past year and a half!!!
Again, I HATE T-MOBILE!!!!!!!
