Cannot Port number after paying up my accounts

I call the cancellations department on the 8th feb to can el my 2 contracts with cell c I was then informed by the agent that I had the option of paying up my account and would then be able to migrate my numbers to prepaid as I wanted to port both numbers to another service provider. I was told to deposit the balance outstanding on my contract which I did on the 12th feb and I was told to call back the next day which I did and was the. Told that my numbers would migrate to prepaid which I requested to be done on the 27th feb, I was told the payments had been received and all was in order! In then called in on the 26th feb (today) to ask for both numbers to be migrated to prepaid as my new phones arrived again I was told all was in order and that both numbers would be migrated in an hour! This did not happen and I recieved a text on both numbers saying the porting had been declined! I then called the the cancellations dept only to be told my one contract only expires on the 8th March (bear in mind I had paid both contract up to full term!!!) I was transferred to every department and no one can resolve the issue! This is holding up my new contracts now! I want this resolved urgently!
