CELL C - TERRIBLE SERVICE

I upgraded my Cell C contract which was the worse mistake of my life. I upgraded to a router (which wasn’t explained to me proper) a day after I realised that I would need to put my sim card into the router in order for it to work, I called Cell C they advised that I am correct and that they do not have a dual sim card system available. I decided to cancel my upgrade and requested to move back to prepaid. I have made almost 15 calls to Cell C and I still cannot get any joy. Every time I speak to a new person, I have to do all the security checks again, which is soo annoying as surely if they transfer you internally you should only do the security check once. I now cannot be migrated back to prepaid, I have to wait 30 days, and every time I need data or airtime I must call Cell C to load. They cannot even tell me what have I already taken on my account and give me an estimate of what my account would be at the end of the month. The call centre people sound as if they are still asleep you have to scream and talk to them. Once my contact is cancelled I will definitely change my network provider, I cannot deal with such an *********** company.
