Request to Cell C

I am a client of Cell C, the cellular service provider, with whom I have a cell phone service contract. The contract was to end at end of March 2023 and a renewal of contract to take effect on the 1st of April 2023. According to my understanding, the terms and agreements of the contract allows a customer to request changes to the new contract prior to contract renewal date. On 10-01-2023 I requested Cell C customer service via 084135 that the contract on renewal be changed to a "month to month", so that I can give a month's notice to further change it to a prepaid service. This request was accepted and acknowledged via email (proof of which, I possess). To my disappoint, in my April 2023 Billing statement I noticed that the contract was changed to a "12 months" contract and not a "month to month". I am not aware of any notifications from Cell C in regards to the change in my request.

I have had numerous communications (phone calls and emails) with Cell C requesting that the above be rectified (contract be changed to "month to month") but to "no avail".
