PORT NIGHTMARE

I have been trying to port back from MTN to Vodacom since last November. Since then i have no Joy. Everytime i call in its starting over to sort the issue out. MTN SP says the problem is not there side as they are not getting requests from Vodacom to port out the number. I have had sevral agents tell me they have escalated the problem to the service desk and to date i have had no response. I have been chatting to the person on Facebook and also stated they have escalated the matter and now i get ignored. Why is it so difficult to assist someone. If it wasn't for the better roaming options and signal i would have not even bothered.
