Disgruntled customer

I downgraded to Access subscription during COVID and have been upgrading once a year during the holidays. I bought an Ultra Explora decoder through Multichoice 24months ago and being billed with my monthly subscription. Sometime in Jan 2023 when I wanted to downgrade with Multichoice and was told about a contract I never agreed to. Their explanation was that the Ultra Decoder special went along with that contract. Okay I thought my bad I did not READ carefully then. I was told it is left with only 4months and maybe just stick with it for me not to lose some discounts of which I never even realised. Okay fast forward it's the end of April , I am done paying my 24months contract for Ultra Decoder. My debit order goes off on the 26th of every month. I tried to downgrade yesterday on the app since I will be away most of the month and now I am told I am on a contract and it's left with 22 months to go. How is it possible that I am on a never ending contract I did not agree to or heard of. Their calls are recorded so where is the recording where I renewed some contract I've never even heard of. Once more I am being told of discounts I do not even enjoy, never experienced and worse of all they are unable to name them . I am paying the normal prices and they have since increased hey. I called Multichoice this morning to be assisted with the downgrade and still waiting to be assisted. How is this possible?Who is enjoying discounts at my inconvenience. What discounts nogal?
