Telkom Service =non existing, Penalty charge

I upgraded my LTE Package with Telkom. As my application for the upgrade was in process, the Telkom employee said there are no penalty charges as long as you are upgrade your package. Received my Telkom invoice, Penalty charge of R1540, Went back to the branch and they put me on there care line. The Telkom employee on the care line would sort it out and the penalty charge was a mistake. Debit order went off my account without the penalty being removed. Never liked Telkom and This confirmed to me how useless they are.
