I have been with cell c using their contract, now I called in to cancel my contract since I'm no longer interested in their services, after a few days , a cell c contract line calls me to advise me to upgrade, I then told the consultant that I have canceled the contract few days ago, he then advise ls me that nothing was done, so the previous consultant ****, then the same person immediately hangs up so that I don't get a chance to resolve this. I understand that cell c I having financial problems and stability, but so is everyone, I can't afford their poor service network. Cell c cancel my contract now
