Telkom Mobile not cancelling my contracts

Called for contract cancellation 3 times as my contract period is up for two (2) of my telkom mobile contracts. The call center transferred me to +-4 departments yet nobody assisted me.<br> <br> I have been to the Cresta branch, yet they told me to phone the call centre. This is unacceptable as I am being charged for a service that I do not want anymore.<br> <br> Please someone sort out my contract issue ASAP. If a debit order goes through I will return this at the bank.
