Impossible to cancel my contract after 2 months of repeated attempts.

My contract with Vodacom ended on 30 Dec 2020. I have been on an expensive RedVIP package and have been a customer for 20 years. I decided not to renew my contract due to the cost and did not want to be locked into a contract.

I can't cancel my contract, they make it almost impossible. It can't be done by email or text, only by calling their cancellations service. 3 Months later and I am still racking up an expensive bill. This, despite 8 calls to the call centre and 5 broken promises to escalate and call back followed by a confirmation SMS...nothing! It's simply disgusting that such a professional company will do anything to upgrade you but nothing to stop one's contract!
