Telkom SMBS Retention Centre not cancelling Telkom Business Accounts

Telkom SMBS Retention Centre is the most ineffective department in Telkom we have dealt with thus far and shows little to no intention of assisting in cancelling client agreements. Submitted cancellation to Telkom on 14 March to *** on a letterhead. 3 separate cancellations, 3 separate emails, separate cancellation letters, one for each account, and they are still not cancelled! Debit order still goes off every month. After mailing the cancellations more than once, we have contacted Telkom on 10217 and 10210, and get pushed from call centre to call centre, each of those referring us to the other. We eventually found 2 separate people willing to at least give a direct email, yet we still have not had any joy. Several emails, calls and MONTHS later, Telkom is still debiting the account and now we getting no reply to any emails. Every email and call that actually got rep**** to asks EXACTLY for what we sent in March, and we forward it to them, with no change in the result. Even worse there is no escalation number / email that we can find to escalate to so that Telkom can actually be held accountable.
