Impossible Telkom Line Cancellation

We have been trying to cancel our Telkom line for over 3 months now. The online cancellation did not work, so we sent an email with relevant documents attached to ServiceCanOut.telkom.co.za, as advised telephonically by Telkom and cancelled our debit order. We did not receive a reply and they are still trying to charge us. We have been trying to call various numbers, no reply. Have also sent a Facebook Message to Telkom. I have done a post on Facebook and have had innumerable replies of people who are/were having the same problem. For some it took over a year to get it cancelled, some are still waiting for their refund.
