Telkom wont process my cancellation Request!!

I've had a terrible experience trying to cancel my Telkom mobile contract. I submitted my cancellation forms via the web interface and got a reference number stating that they received my cancellation. I did the cancellation within there specified minimum 21 working day requirement. I Called the call center a couple of times to confirm that the cancellation has gone through and they say they haven't received the request! Then sent them the cancellation request forms again and they still have not processed the request!!!! I will take you to the CPA and report you to ICASA if this does not get resolved ASAP
