Unable to port number from Cell C to MTN

I am in the process of getting a new contract form MTN in my name. My current contract is with Cell C, but is in my father's name. My contract with Cell C ended at the end of September, after which it continued as a sim-only contract. My father went in to Somerset West Cell C on 27 October 2015 to give a month's notice to put the contract onto prepaid. <br> <br> My application for a contract with MTN was successful, and all that's left is for the number to be ported from Cell C to MTN. MTN attempted to port my number today (more than a month after my father gave notice to go onto prepaid Cell C), but the port was rejected by Cell C. <br> <br> As the Cell C contract is not in my name, no-one is able to provide any information on why the port was rejected. My father is also incredibly busy, so he isn't able to chase after Cell C. Can someone please assist me with this matter?
