Contract reversal after cancelling Upgrade

Hello Peter Cell C gave me an upgrade and I decided to cancel it duringn the cool off period as stipulated in their contract, then I had to return the phone and I did it was still sealed. I called them to migrate my number to what it was before and they took me through the process and I was told it might take 48 to 72 hours. I then call after I realised its not going back as usual I was sent form Pillar to Post, the next thing I speak to a consultant at their Uprades department who tells me that she doesnt have the similar contract that I have been using for the past 23 months she is putting me on another contract. I then disputed to say that I want my number back to what it was then she starts shouting at me.

I must say ever since I have decided to cancell my contract with cell ce I am being sent from pillar to post and the consultants are being very rude. I am not sure whether its their way of saying they dont care about clients that are leaving or constomer service training is not sufficient. Anyway I am glad I am leaving them , but I need my number on a prepaid for now before migrating to another network. I am not sure I can keep up with such poor service and bad attitude.
