Cell C is ****ming its costumers

I have been a Cell C customer for the past 8 years, which I never had a problem with until I had to cancel my contract. I called Cell C in November 2022 to cancel my contract, and I was advised to call again in February 2023. I was told that I would have to pay a late cancellation fee of R90. How do I pay for a late cancellation fee when I have requested to terminate the contract in November 2022? Cell C is punishing its customers for terminating their contracts. I received my statement saying I now owe R190, and on top of that, this is on my credit report.
