***** with my name

I phoned cell c customer care it was March because I saw there were not deducting their money on my account n they said I have 3 phones contract with them and since I sign for my contract I told them that I want them to deduct their money.But the person who did a ***** with my name changed everything they said I'm paying my accounts cash.They said they gonna open a case n give me referance number *** after that they ask me to send affidavit,3 months bank statement n copy of my I'd I did all that after nobody came back to with a feedback.The other thing is that they were deducting R288 per month for my 2 contract but they told me now I have to pay R315 I don't know now y do I have to pay so much money.So please tell them to fix everything with my accounts so that I'm gonna feel free because what is happening to me is stressing me coz they always gonna close my phones each and every month even if I payed them the normal money that I have to pay.Thank you
