Vodacom Cancellation Worst Service Ever

I phoned Vodacom to cancel a contract which expired on 27 January 2021 on 6 December 2020. I was given confirmation via phone that this will be done, I was billed for this same contract in Feb 2021 and phoned Vodacom again and spoke to Nokukhanya which said the contract will be cancelled and I will be refunded for February it will be send to escalations. In March I was billed AGAIN for the very same contract and I had to phone again on 23 March 2021 and spoke to Kerry who promised that the matter will be escalated and the contract cancelled as per my original request and I will be refunded I must wait 2 days for feedback. Today is the 30th of March and I have not received any feedback from Vodacom. This is truly the worst service ever and I will not be renewing any of my other contracts with Vodacom once it expires even though it is a impossible and painful experience. Seriously, Vodacom is eager to help with a new contract but it is nearly impossible to cancel one. I really hope that this matter will be resolved ASAP and that I will receive feedback.
