Telkom refuses to cancel Month to month

I called the Telkom customer services departments on 3 Jan 2018 to cancel my LTE contract.

I completed all the forms and sent it Cancellations

No one contacted me so I called them at end of Jan 2018, I was then told that it was not received and sent it again with the original message .

I was told that there was still no feedback/update on the case even though I have logged 9 escalations about my cancellation request.

I have still not had any feedback nor confirmation of the cancellation. My new invoice still reflects the charges for the contract and it seems like Telkom does not care about their customers and have no cancellation process

They are absolutely useless as it is now six months from my cancellation request and I am still being charged.
