Cell C Upgraded my contract without my knowledge and consent.

I have been struggling with No Cell C network even though I am religiously paying my account. Cell C is not delivering the service (connection) that I am paying for. I contacted cell C to give notice on my month to month package as my Contract expired in 2021. I was informed that my contract was upgraded to a data contract in 2021 and that I would have to pay a penalty if I cancel. I did not give my consent for this updated. I have been waiting since Aug 2022 for feedback on this matter and have created a new case on 30 Nov 2022 and again on 22 Dec 2022 and I am still awaiting feedback. I call back daily for feedback and the only reply I get from the agents are that I will be called as soon as the case has been worked on. I daily ask for a Manager or Supervisor to call me and every tine get told that they will call me, I however have to date not had any manager / supervisor call me. I even went as far a lodge a formal complaint to the custserv email address as advised by the agents and this complaint case number was closed with no feedback to myself. I again last week Friday 6 Jan asked how I can complain and I was informed that I can call the Customer Service team to complain and I asked the Lady if she is not in Customer Service and she said yes she is. I then said I would like to complain and have this escalated and she informed me that she is unable to assist me in this matter. It seems like it is impossible to get anything out of Cell C. I have *******ly been placed on a contract and want this cancelled without paying an early cancelations penalty immediately.
