Cancelled telkom line but still being charged

I cancelled my Telkom landline after waiting for over an hour in the Telkom walk in centre (standard operating procedure for Telkom - great fast customer service).<br> <br> I then found out that Telkom did not cancel my account so back I went to Telkom to get my landline cancelled - another hour wait.<br> <br> This time I got an sms to confirm that my cancellation was being processed.<br> <br> And now my landline has still not been cancelled. Obviously its impossible to call the Telkom call center since no one ever answers. I will not go to the Telkom walk in centre to cancel again only to be ignored. I refuse to pay for one more day of Telkom. Thank goodness fibre has made it possible so that I no longer have to deal with Telkom. But it is really unfair that Telkom makes it impossible to leave.
