Telkom does not process Cancellation requests sent in via EMAIL!

I put in a request to cancel my account on the 7th of May, I received an automated e-mail that it will be processed. Since then I have been rebilled the following month.

I have tried to make contact by filling in account disputes on their site. I have asked them to call me to resolve the issue. I have e-mailed one of their chat agents as well to no avail.

I have e-mailed their accounts department only to receive automated e-mails.

I have phoned their number and stayed on the line for nearly an hour after getting constantly disconnected waiting to speak to agents.

I have not once been contacted by Telkom to resolve this issue, nor have I been given any clarity/information/emails as to why none of my previous requests have NOT been processed.

I cancelled a service and now I am still being billed and debt collecting agencies are now phoning me for NO REASON!
