Sim Swap - no service for a week

I lost my phone on 27 October 2015 and did block my sim card at cell c. After buying a new phone and sim card on 29 October 2015, I phone the customer care line 084140 to do a sim swap. I already made 17 phone calls and about 8 emails I have send them. Each time the agents have a diffrent storie, the phone will be working in the next 2-4 hours, then the other one said it will take between 24-48 hours. I'm sick and tired of this matter with Cell C, it's the worst service I received from them. I really like Cell C, but after this I think I must change service providers. I am working for the SAPS and need my phone for duties on my shift at the police station. I need urgent assistance please. It's more thank a week now, what could be the problem?!
