Contract gets extended beyond 24 months even after cancellation notice was sent.

Good day,
I would like to cancel both of my contracts with immediate effect, thus I need the amount to be paid to enable the cancellation. I have previously requested cancellation of my cellphone contract ****, but I have had no assistance at all. I went into agreement for this contract on 25/08/2019 and it was supposed to expire on 25/08/2021, but I continued with my contract. I requested cancellation/termination of my contract two months prior to the 'renewal' of my **** contract which should have been cancelled on 1 August 2022, but was not. Now the contract has been extended to 1 January 2023 without my permission and I have debt because I could no longer afford the contract which I tried to terminate as per our agreement.
I also want to cancel my contract for **** immediately and need the SETTLEMENT amount of the contract that should expire next year March 2023 as per your automatic phone call service-which I have recordings of. Per your agreement cancellation of my contract should only cost R960.48(75% of my ****contract) + R1518.04 which is my outstanding balance. Kindly provide me with a settlement amount and letter PER EMAIL as I want proof thereof.

I will be following up in one week's time to ensure that my contract can be cancelled as requested as soon as possible.
You are definitely losing myself and followers as a customer due to your inability to actually assist your customers.
Regards
