UNABLE TO CANCEL TELKOM LINES!!!

We cancelled two Telkom lines for two bodies corporate that we manage in July 2015, for which we received NO response from Telkom. Feeling somewhat frustrated we decided to take the most direct approach, irrespective of the massive inconvenience, and went into the branch itself on the 2nd of Oct to cancel these contracts again. The cancellation was confirmed, but Telkom proceeded to send us an account on the 20th of October in any case! We phoned Telkom to make an enquiry regarding the account (have you ever tried to phone Telkom? They ALWAYS are experiencing high call volumes, which is no surprise seeing as their service is less than satisfactory!). We were then informed that the reason we received an account was due to our line still being ACTIVE! They said they had received no cancellation documents. We paid the account and once again emailed all documentation through to Telkom and logged a dispute to the escalation department on the 18th of November. We received no response. Big surprise. Today, the 28th of November, we contacted Telkom just to find the line contracts are still not cancelled, and Telkom ONCE AGAIN requested the cancellation documents. BEYOND FRUSTRATED!!!
