They said m now in areas with R790 in July well I paid it all in August i call called them again to advise that I have done the payment I was told to email the proof of payment to customer care who I did . Now in October they sent me a final letter demanding the payment I made in August. And they are affecting my credit beura scoring because the handed me over for payment I did three months ago. I also sent this proof of payment to ***.

Really not happy I would not even recommend any one I know not to engage with cell c .
