Cell C customer service

I called in to do an urgent sim swap and was told to call again since some information does not correspond when I'm sure about the info . I called again in the next few minutes when I realized I mixed my recharge dates. When I call again the next agent, Zimbini Zikhali as she said, tells me she can't help me , she can't verify info i must go to the store . Which is very strange because the first agent verified the info . By her tone and questions I could hear attitude, and when I escalated she told me there's no supervisor I can speak to or anyone superior. I was not calling from a cell c line ,I called with my airtime and needed help and I explained this to her . She did not even try to help. When I checked online(https://mybroadband.co.za/vb/showthread.php/522477-Cell-C-SIM-Swap-Which-SIMs-can-be-swapped) it does not say that for a sim swap, the calls made must be not older than 3months and to solve the issues you must go to the store . If it did I would have saved myself from the bad service I got. We have busy lives and cannot go to the store for something we could have resolved over the phone . Calling Cell C customer service was a complete waste of time and money. Why must we use your services when you can't offer the support needed to use the services. This is poor customer service by Cell C and not helping the customer .
