Pathetic service - Empty promises. Where is my refund?

Still no response from Telkom with regards to my refund on two cancelled accounts Numerous calls of an hour each, stood in a queue for about an hour at the store to report the problem again, numerous emails to Telkom. Its been four months now since my initial request - no joy whatsoever. BUT the marketing department still call almost everyday to offer upgrade, even after the contracts have been cancelled but no one gets back to me about the refund. Pathetic service.
