Nightmare when trying to cancelling Contract.

Contract cancellation is a nightmare. Just canceling my contract with them was a nightmare. I was convinced not to cancel. Rather take another affordable package to which i agreed but immediately regretted my decision. Thereafter, I cancelled again that this was beginning September 2024. I am still paying a contract that I have never used. When I call to follow up cancellation or query my refund my bill has trippled for the month of November 2024. Is this nightmare ever gona end or should I just reverse and stop debit orders. NOT USING VODACOM EVER AGAIN.
