MTN to Telkom Mobile Porting Failure

I have been trying to port from MTN to Telkom Mobile for the last month and a half, I have been to my local Telkom Mobile store about 15 times to do the port. The port has indicated as successful every time but fails during the 24 hour waiting period. We have changed the details of the port to those indicated by MTN to no avail. I have emailed the Number Portability Company of SA who say that I must speak directly to MTN. At this moment I have been holding for 22 minutes on one line and 14 minutes on another line trying to speak to my Credit Controller which [Email Removed] says is the person I must speak to. I no longer know what to do, I need this number transferred as quickly as possible please.
