i have had a contract with cell c since november 2014 aswell as insrance from c surance. My phone was damaged in december and when i tried to claim, was told that i am not insured which i was. I called c surance (cell c's insurance company) everyday till they pulled the call for when i requested insurance. It turned out that the agent didnt capture my details for insurance although i had requested it. After the investigation ii was quoted my access fee then in February i paid it. The handset i had taken out was discontinued so i was offered another but would have to pay the difference, which i then paid in March. I chased up on this claim everyday for 2 months, being told that it would take 3-5 working days originally. I was told that they couldnt find the proof of payment for the difference in price for the handset which i faxed 3 times from a cell c store in Golden Acre. After this i was again assured it would take 3-5 days for me to get my handset. When it didnt arrive i was then told the claim wasnt successful (in May) no one bothered to call me or update me and although i have now received the handset they still havnt sent my sim card to go with it!
