Inability to cancel my contract

From July 2020 I started trying to cancel my contract, I was told the contract ended the 15th of November and I could only cancel it from the 16th of October. I called cancellations and spoke to Zinhle, she told me the process, how I would still be billed and debted another month post the contract ending November 2020. The final bill would be smaller and my data, minutes and texts would not immediately be lost and they would roll over for one month. I asked if my number would be converted to pay as you go and when that would take effect. Surprise surprise I have recieved January's allocation and no evidence of my cancelled contract in October! Costomer Care tells me I have a valid and automatically processed month to month contract and nothing reflecting my cancellation on the 16th with Zinhle. Here in case, my reason for desperately wanting away from Cell C, the inability to be consistent and poor service. What more do you need from me to let me go? I do not want a Cell C contract
