Not transparent with fees

On the 28th of April 2023, I got a cellphone contract with Cell C. The consultant that assisted me on that day told me that the price of the device I qualified for is R489 in total. And that I am required to pay some additional once off fees(which I agreed to). I requested that she also adds on the insurance and she told me that I don't qualify for the insurance. I later had to call the insurance myself in order to get my device insured. My first debit order went off the following month and all the fees that she said would only deduct once turned into recurring in month 2. At some point I thought maybe there was some sort of miscommunication with me and the consultant. But on the day I got the device I was with my mother who heard everything that was said to me by the consultant. My mother confirmed that the data was indeed free and that I won't be billed on Calls and data. In May I called in and requested the agent to cancel everything that was on my bill and I want to pay for the device and insurance only. And she claimed that they will be inactive after 30 days. I am on month 8 and I am still paying for subscriptions I am not aware of. Please give me some clarity on this.
