Tracker *****ing after cancelling a contract

Kindly explain how you arrange to debit a cancelled account? You sent the confirmation letter and then again this send sms's and statements for the same account to be debited and with the wrong amount again, the expired month to month contract was for R179 and you debit R331,76 because you can and you will because calling your useless contact centre does not seem to work where one is **** to and told its cancelled and no more debits will be taken yet you place another debit on the account, fix your **** and stop taking peoples money. This is my last request I am sending you regarding this cancelled account, I will seek help to report you on a higher level if you proceed to run that debit.
