Terrible Service from Cell C

Trying to do a sim swop I was advised to get a new sim card and Rica it, then was told later that it should not have been rica...called the call centre for assistance spoke consultants that said their manager would call me back by 12h00 but no call. I called back then spoke to Olga, Precious Mkhize and their Team Leader Dineo who did the same security check. I am 67 yrs and fell and my phone fell in the toilet got damage to now because I cant remember the last numbers I called nor the amount of airtime I last put in my phone I CANNOT DO A SIM SWOP I was told to go to cell c office. I find this as Bad Service and will be changing networks. Terribly Dissappointed
