Impossible to Cancel a Telkom Service

Telkom cancellations is a mess. They don't understand their own processes. The shop advises to use the myTelkom application but SMBS Telkom Retentions (Tsholo Tlhapane) advises: "forward your initial cancellation request...to be on a Business/Company Letterhead that with relevant ID Copy(s)" without any negotiation.

I question why if I have the cancellation acknowledgement from the myTelkom app and get a one-liner: "Alright then." Asking what this means she responds (in bold): "I am not in the Billing department to assist with any Billing related queries." She suggests: "kindly email Billing on ***".

So, what happens if you do? The result: *** The recipient's mailbox is full and can't accept new messages at this stage. Message therefore not delivered. Please try resending this message later. [Telkom SA SOC Limited. Registration nr : ***].

Go figure!

Cancelling a Telkom service seems to be impossible, it's like leaving a Las Vegas casino. How do you avoid this? Don't ever take any service from Telkom if you don't like regrets.
