Contract breach, theft and harassment

I experienced very bad technical service delivery from Telkom for internet services. Their service was not inline with the contract specifications. I the contacted Telkom numerous times to log a complaint and a service call, but received no response and no action, even after speaking with a manager.

Finally, after months of the poor service, I contacted Telkom again and submitted an official cancellation notice, on the official form provided to me by Telkom. The cancellation notice was submitted in Sept 2017.

Each month since then, Telkom have continued to take a debit order from me. The most recent debit against my account was yesterday. I have contacted the call center numerous times, spoken to countless agents and submitted the cancellation form again and again (for which I received confirmation of the receipt thereof). I have asked for a manager to contact me and not once has anyone called me back.

Telkom is effectively *****ing from me by taking unauthorised payments on a continuous basis and completely ignore me when I call and email to resolve. As i write this, I have been on hold with the cal center for over 20 minutes.
