I had a contract with Cell C from 26-01-2017 and was supposed to end 26-01-2019. Pre the 26-01-2019 one of the agent called me advising that my contract it is about to end and asking if I would like to upgrade or end the contract and my answer was to end the contract! June – 2019 I discovered that Cell C is still debiting my account and they are debiting more than I was paying during my term with them then I kept on reversing. Now I am receiving communications from them informing me that I owe them R -2,833.50. I am not sure if I must pay for the services that I am not rendering and I am afraid that they are going to black mail me if I do not.
