Disgusting service and extension of contract with my knowledge or consent

This is the second month I have been trying to cancel my vodacom contract but vodacom decided to extend my contract that suppose to expire in February 2022, has extended it till December 2022 without my knowledge or consent. no emails, no sms, no proof at all that they will be extending it and now after settling an amount I was told that they would cancel the contract in February 2022. Aftwr being promised that after paying this settlement amount they would cancel my contract I'm now going back and forth calling everyday to get assistance with canceling this contract. I have paid 8k already and when my contract was on monthly debit plan they would take 4k some months 3k the next month and I stopped the debits for this same reason. I need some professional help as now I'm told I need to pay another 4k to cancel my contract. When I call in and speak to an agent after waiting up to 30 minutes to get through to an agent the agent will tell me they can cancel the extension as that not suppose to be they say they have canceled it I need to wait for 2 days and they will call back to confirm if the canceled has been done does that even make sense? but when I speak to another agent on a different day one agent will say that they cannot remove the extension. What in the hell is going on? After paying an additional amount after settling the 8k vodacom adds on another amount that's shows outstanding on vodacom app. Now I am really confused and starting to get really ****wd off because vodaxom rips people off and thinks we have money lying around waiting to give it to vodacom and get nothing in return.

I need some help in this matter as I cannot run around back and forth everyday with no help. Vodacom agents are disgusting and unhelpful. They never give a reason why as to anything u ask and they never send emails to you why?
