Renew contract without consent

Cell C just decided to renew my contract without any consent or correspondence. When I spoke to a rude consultant, I was requested to go to a police station to get an affidavit to say that I haven't renewed the contract. I have my own business, and I do not have time to go and stand in a que to do this. Are they going to reimburse me for the business lost while I have to stand in que for their incompetence. How is it not possible for them to review the contract, and see that this was not signed for, or any consent was given to renew this contract. I thought calls were recorded? I have to send a plethora of proof to renew or upgrade a contract. never mind the 20 questions they ask to confirm identity. How is it possible they still make these mistakes. It's just a ploy to get you stuck in another useless contact and to charge you for cancellation etc.
