Poor service from Telkom

Absolutely poor service from Telkom. I sent through cancellation forms in April, no response. Sent again in May still no response. Sent in June and finally got a response requesting cancellation form which was filled in and sent. I phoned billing to process a refund. When i got my bill i was still being charged. Billing told me that the TIN number was not added in and i had to get it. Spent almost 2 hrs getting it. Phoned Billing again to re-submit, explaining the whole situation again. Submitted request but when i asked if the cancellation is being processed, i am told that no request is on the system. Really tired of Telkoms ****!
