Impossible to deal with, debited me after canceling

I called to cancel my account on the 8th October. I was assured it was canceled from 1 November and I would not be debited.

Surprise! I was debited this morning 2nd November nearly a thousand rand, and despite trying to call the call center for over an hour I cannot talk to a human to cancel AGAIN and get my money back. The call keeps dropping and the first menu option is to reconnect. I thought it was to reconnect the call, but no, it's to reconnect the account I cancelled last month. Now I'm stuffed, paying nearly a thousand rand for a service I canceled a month ago and cannot get rid of.
