Bad customer Service at Cell C

I am utterly annoyed at the poor service from cell c. I got ****** a few months back, despite dealing with the trauma of having lost my cellphone and wallet, cell c has been sending me from pillar to post just to get a sim swop! Can someone please tell me where to get a SIM card that is not ricad? I have been to cell c store Menlyn 3 times already no one is able to assist me. Even the consultants in store don't seem to know where to refer me to get this unricad SIM so that I can do the telephonic SIM swop. What needs to happen to for me to be assisted promptly? It already has been 2 months and time is running out. As we speak I am losing clients as that line was connected to my business account. I have gone to great lengths to collect the verification information required for this sim swop and yet still I have not been assisted. Just to be clear... I want a SIM swop and someone needs to tell me where to buy the SIM card that is not ricad surely a reputable company like Cell C should be able to assist me we with this issue promptly. This is unacceptable if this is how long term customers like myself are being treated.
