Can’t get number powered to Cell C

I have always had good service from Cell C but my latest contract has been a real problem. I app**** and received a 2GB TopUp contract at the end of May with a request to port a number from MTN. The device had to be replaced and it was. However the number has not been ported. I have called and requested the port. Then was told to get a new sim and so went into store and bought a new sim to request the port. Still not done so I went into store and was advised it’s still porting.

I am now very frustrated as it is a month now and I am not getting anywhere. Can anyone assist?
