Cell C incompetence

I have now been trying to do a sim swap for 2days. When I phone the customer care line to assist me with the sim swap, I get told I give them the incorrect information. The scary thing is that I read all the information that I give them from my upgrade documents, which I did in December 2021 and I have not changed any information since then.

I have my own business and I am loosing business due to my sim card not working correctly and the incompetence of Cell C is astonishing.

I would love to change to a different service provider, but due to my contract that was just renewed, I cant do that.

I would not recommend trying to do any sim swap or anything important/urgent through the Cell C customer care call center
