PLEASE CANCEL MY CONTRACT

Cell C contracts are very misleading. I took up a contract for a Samsung A31s in 2020 for R324/month after 6 months it became R393 with an allegedly GETMORE service that I never signed up for. After enquiring the customer service was always rejecting my calls stating I couldn't pass their so-called verifications. Went to a cell-c store and my contract was on an entirely different name, different address, HOW IS THAT EVEN POSSIBLE??? They partially fixed it and since I recently received my ID I wanted and at the store, they asked me to call the customer service and the customer service also asked to go to the nearest store. Been in that loop for almost a month. I WOULD LIKE TO PLEASE CANCEL MY ACCOUNT, I have paid the remaining money and sent the proof of payment. I WILL NEVER EVER MAKE A MISTAKE TO EVER TAKE A CONTRACT WITH THEM, very misleading and so many hidden fees. No transparency and rude agents.
