CONTRACT CANCELLATION SENT - TELKOM IGNORED IT NOW THEY WANT TO CHARGE ME.

I logged a call on the 13th April to advise for my line to be cancelled.

No one from Telkom has responded to my call, till-to-date.

Agents from debt-in are calling me requesting funds as my account has been handed over, yet i did follow the process the Telkom consultant told me to follow.

Why is Telkom not responding to my cancellation email? Why is my account handed over for an error on their side?
