after telling them i am leaving the country on 02-04-12, so end service at this time. t-mobile continued to deduct payments from my bank account. called from southern mexico, and was given a cancellation number this time to assure business is ended. received another bill on 03-23-12 taken from my bank account. my original account with them ran out a year and a half ago. but i was still on a month to month plan. they don't like you to cancel with them.
