Contract cancelled in March 2020, still paying + upgraded without consent.

Good day, In march 2020 I cancelled one of my Vodacom contracts, I still have two other active ones and this one was no longer needed (The number to cancel - ***. I called Vodacom, followed all the procedures, and proceeded to cancel the contract with the gentlemen. The following month I saw on my account that it had not been cancelled, and instead upgraded to a Uchoose Felxi 65, I had never heard of this and did not want this as I made it very clear that the number should go over to pay-as-you-go. I again phoned Vodacom, eventually got through to a lady who said she would reverse the unauthorized upgrade and put the contract onto pay-as-you-go. There was a query opened, that then said resolved, but its not resolved. Another month passed, I was billed for the Flexi 65. I called vodacom again, explained the situation again. I checked my statement and saw that now instead of the contract being cancelled they AGAIN upgraded my contract to a smart top-up S, and AGAIN this is going to be charged. I again logged the issue and a second query was opened that now shows resolved, but it is NOT resolved.

Guys bottom line, I cancelled the contract in march, since then I have spent an awful amount of time calling Vodacom to do their part. Since march I have been billed for two unauthorized contracts and received no feedback at all. This needs to be resolved asap. I can be contacted on my main contract number *** Christiaan
