Daylight ******* from Vodacom Fibre

I am so fed up with Vodacom. They are doing daylight *******. I took a Vodacom fibre contract for 1-year month-to-month agreement which was ending in June 2023. I called them on the 1st of June 2023 to cancel. I was informed that it will be canceled at the end of July 2023. I called today to verify if it was canceled. I was told that I am now in 24 months contract, which I never agreed to it. I am so ****ed off with Vodacom and their lazy agents. I need proof that I signed that contract otherwise I am taking Vodacom to court for the daylight *******. Please cancel this contract as I have already issued the required notice. How can I pay for something that I am not using?
