Contract cancellation

I have been asking vodacom to cancel one of my contract with them, and they keep telling me they are doing it the next thing they are sending me a route for the number I asked to cancel so many times, I spoke with many agents from 21 May 2023 til 31st May 2023 asking them to cancel the contract, next thing they tell me they have upgraded it, on whose permission I don't know, they are now forcing me into a contract that I do not want anymore they are better deals out there now and I'm done with them on that contract, they are like an ex that do not want to let go, is over accept it. Today checked my account they loaded the number with data but I don't want it, I'm not going to use it, I want it cancelled
