Is it possible to CANCEL a Telkom line?

I have been trying for 5 weeks to cancel my Telkom Business landline. I have emailed [Email Removed] a total of 37 times and I have not had a response, not even an automated response.<br> I have tweeted, reported it to Hello Peter before, I got no response back. I phoned 10217 at least 20 times. There is no option on 10217 to cancel a line. I spoke to the accounts people, they say there is no cancellation department. I have been to a Telkom Direct Store. Nothing. SO, how does a person cancel their Telkom Business landline?
