I cancelled my contract early as I was having problems with my service and paying considebly more than with my last provider. I was told I had to pay a fee for early termination and I was ok with that. To my surprise, they also billed me a whole month and gave me different answers as to why. Finally, I was told that the charge was because I was taking my number with me. But, guess what? I had transfered the number from my previous provider to T-mobile!
