Cell C won't Stop billing me! Please help

My name is Reginald Rakhetla and I signed a phone contract with Cell C. The contract was a month to month contract, meaning that, should I wish to cancel the contract, I would be able to do so according to my contract. I contacted Cell C and informed them that I no longer want the contract and would like to cancel a month after payment as per our agreement. I did that four months ago and they are still debiting money from my account, from the day I called till to the present day which is four months.

They are honestly ruining my credit score and are an inconvenience to my life at this point.

I would really appreciate your help in tackling this problem, freeing me from them and finally exposing Cell C for what they are.

I look forward to hearing from you.

With kind regards Reginald
