********** Renewal of contract

I entered into a contract with cell c on a month to month data contract for R384.32 and my account has been debited for the past 24 months the same amount. During the month of February 2023, my account was debited an amount of R911.20 and when I enquired why I am being overcharged, I am informed by the consultant that my contract was renewed. What is surprising is that the contract was renewed, however the benefits remain the same but the amount has more than doubled. when I ask the consultant to cancel the contract because I did not initiate the renewal of the contract, I am told that I must do an affidavit. When I asked who renewed the contract and why don't they get the recording from the person to cancel the contract, I was told that they don't know the consultant and don't have the recording and I should do an affidavit at the police station. Why should I be inconvenienced and leave my work to run around to police stations just to do an affidavit of something I know nothing of. What I want is for the contract to be canceled because I did not initiate the renewal and I want the recording of the said approval where I gave permission for the contract to be renewed.. When sales people are calling they always say that calls are recorded but when its time to pull out the records we are told they are not available. The cell number of the contract in question is ***.
