Sim swop

I simply need a sim swop but the service I have been getting from 11 of the agents I have spoken to is bad the last one kept rising his voice. I'm on contract what more do you want from me. I would cancel my account if I could I recommend Cell C to people but since Monday evening I haven't used my phone and on Wednesday I spent my entire day try to get a sim swop done. I understand that they needed to call me after 4 hours but I didn't have an alternative number so after 4 hours I called back so they could help me get it done Back Office thing is getting on my nerves I don't know how it works but today is the last day I need to get my phone working my life is on hold because of the service I don't have 24hrs to wait since Tuesday 5 am I called bought a new sim card and then I lost it because my mind was spinning now I had to buy a new one and I'm not sure whether they were listening to me when I gave them or the thought I was a problem in their lives.
