Cancellation of contracts

I have been trying in vain since July 2023 to get contracts cancelled, I went to the store where I was told I need to phone the Cancellation department directly on the number ***, I did this on more than one occasion. An email I sent was answered by Unathi Dunywa which she said was transferred to the cancelations department. I have been paying over R1000 a month for contracts that should have been cancelled at the very least since end of Nov 2023. I just keep getting ignored. You wont allow me to upgrade to what I need in a reasonable price range, yet you also won't cancel contracts that are way past there contract dates. I am at the point of reporting this further. Please phone me back at the number provided to sort this out. I have issues every month. My notice for cancellation was given months ago, so do not even try to make me pay another month.
