Porting of a Telkom number has been complete unsuccessful.

I have tried to port my Telkom number to VOIP since September with no joy. I have called in 4 time, been transferred from pillar to post, put on hold for more than 40 mins a time. Keep getting told the number has been ported but the number does not work and my ticket keeps getting closed. I asked to speak to a supervisor and got put on hold again, this time for more than 45 mins.
