Contract Closed but money is still being taken!

After numerous phone calls, cut calls and basically bad customer service from Telkom as a whole my fiances mobile contract has FINALLY been cancelled however you still seem to DEBIT his account and he still hasn't received his refund. We even went into your Clearwater branch to give in his banking details and we were told it would take 3 working days, surprise surprise instead of refunding you take more!! This has been going on since last year who do I need to speak to in order for this matter to finally be sorted out!<br> <br> I want my money and I need this to be sorted out once and for all!!
