******* deduction of money

My contract was cancelled on 17 November, exactly 1 month before the end of the contract as per MTN specifications. I was informed that at end December it would still do 1 final deduction, which was fine.

yet this month, MTN has decided to not honor the cancellation, and has instead *******ly debited my account. when trying to phone the MTN support number from outside the country (as i have emigrated) the message goes into a loop (you enter the number, press 1 to accept, then restarts the message)

besides the fact that this is *******, do deduct money from a bank account you are not authorized to do, this is just plain bad service.
