Vodacom is the worst!

This is a follow up from my previous review. Vodacom still did not get back to me after they said they will be in contact, yet they closed the complaint!

My contract came to an end on the 1st of June 2022, I called on the 31st of May to cancel. I wanted to move my numbers over to prepayment. I know I had to call the 1st of May but I was okay with paying an extra month. I then got through to a retentions advisor who sold me a sim only deal for both numbers which I agreed to. I then called in a few minutes later to cancel that deal I just want to cancel the new deal before it all went through. The advisor told me that it was already put through and cannot cancel it now. You have a 14 day cool off period! I want the cancel. Now I am being told that a cancellation form was sent through and it will only cancel at the end of the month and then it will revert back to my old deal then only I can cancel and move my numbers over to prepay. So now I have to pay for my old contract and my new contract.

Why can't I just cancel? And move on with my life and pay the final installment. Why does it have to be so difficult?
