CELL C ***********, UNHELPFUL, CANNOT RESOLVE TECHNICAL PROBLEM ON THEIR SIDE

If my Cell C number is called, the messenger states that my number does not exist. I can make phone calls, but cannot receive any. This has been FOUR FULL DAYS, Ok, so after plenty of calls to Cell C customer service and a trip to Cell C offices, I still cannot receive any calls, although I can make calls. The outcome is, it seems Cell C cannot fix this problem. Another paying customer disappointed. Tomorrow is another work day. Without me being able to receive calls at all. Is Cell C capable of fixing this problem? It seems the call center attendants have the attitude of we tried to help, sorry, your problem. If you cannot reach me, you should know why. Then try alternative number ********** .
