Frustrating time cancelling contract

After all the horror stories you here online about trying to cancel a contract with Vodacom, I thought I had quite a pleasant experience. Phone the customer care line, the agent on the other side was extremely helpful and send the necessary quotes to get my contracts. Paid the outstanding balance in October and thought that was the end of it. There was not debit order in November so thought I was done with Vodacom.

Come to find out they were just waiting until December to charge me again. I've now tried to call the customer care help desk and because I switched over to a prepaid number they no longer put me through to the cancellation department so I can't even deal with a human to help resolve this. This is incredible frustrating and will definitely not be recommending them to anyone going forward
