Inefficiencies of Vodacom personnel

I have a contract with Vodacom since donkeys yrs back which were for my kids. I cancelled the contracts in September 2020 and the consultant who attended to me advised the cancellation will be processed wef October 2020. I’ve been under the impression that the cancellation was processed only to learn that was not done when I app**** for the credit with the banks. I’ve lodged a complaint with them on Monday and they’re not prepared to help me. I’ve also escalated also to their social media department and they are referring me back to cancellations that was unable to assist me. They’re rude and not even bothered and are telling to pay the outstanding amount I’m not going to pay any money because I cancelled the contract and because of inefficient employees I’m disadvantaged This is not the 1st time I have a dispute with Vodacom and their complaints handling is non existent instead they tell you to pay if you don’t want to be listed. I’m prepared to take this up to the courts if need be
