Cancelled service with t-mobile after having them for 7+years, Cancelled on 11/30/12.
They sent a bill for $63.61 which I paid on 12/06/12.
Just got a bill today 01/03/13 for $57.45.
I called and it was explained to me the billing date ended on 11/28/12, so my billing date went two days before I cancelled and that intitled them to charge the full month through 12/28/12.
I explained to them that it would be a very cold day in hell before they would get a nickel from me.
