UPGRADE

I am fed up now with Cell C. Again I am experiencing the same problem I had with my other number. I finally got my device yesterday after doing another upgrade, I received a new sim card hence I no more had the sim card with me. I called Cell C now at 09h00 and spoke to Sindiswe Sthebe and asked to do a sim swap, agai I was advised to visit the nearest branch and again I informed he that there is no nearest branch hence I reside in Richards Bay and the only available branch is in Durban and the lady told me repeatedly that there is nothing she can do as I have to drive to Durban, even if it hours drive but I have too and she said her Operations Manager too said that Cell C as a whole can't help me and there is nothing that can be done. This is now annoying and extremely unprofessional and the lowest customer service ever. My upgrade number is *** and my ID Number is ***3****3. Can I plz have someone to do a sim swap for me as my sim card has no network. What the point of having a device but no sim card. You'll might as well take your device than
