Telkom's horrible exit process

I am utterly disappointed with the process of cancelling my contract with Telkom Mobile. My contract expired and wanted to cancel the whole thing. You cannot even do it over the phone. You have to send an automated email address and the promise to get back to you in 21 working days (was quite shocked at how the basically saying it will take a month to solve your query). And they never do get back. I have R310 being debited from account every month after having sent the cancellation form three times already. And can you reply to the email? Nope. They just ask you to resend the forms again.

Not sure if Telkom is aware of the importance of the exit process in a customer journey. I may have had a great experience throughout the 24 months of the contract, but this totally masks that experience and this moment will be the one I am left with. Never would I recommend this to a friend or family member.
