Vodacom Porting - NO SERVICE DELIVERY

I am currently a Vodacom customer and decided to port 2 of my contracts to Cell C. Vodacom ported the numbers. I am currently now active on the Cell C Network with Cell C simcards. The problem is the somewhere the porting went wrong on one of the numbers. On that specific number it works perfectly on the Cell C network but there is one HUGE problem... My wife can receive calls from any network except from the Vodacom network. When anyone from the Vodacom network tries to phone my wife it says that the number does not exist. The porting took place on the 4th of March. The problem has been reported to Vodacom but to this day, 16 March 2016, the problem has not been sorted out by Vodacom. When I tried to call the porting technical department on ***, both times I held on for about 50 minutes, it would then ring, and then the call ends. That happened 3 times and I gave up. Everyone that I spoke to at Vodacom so far cannot sort this issue out and said they have to escalate it to the Technical department and it will be fixed within 1-24 hours. It has now been 12 days???? I have been to Vodaworld but to no avail, no-one there could assist me. Please help!!!!
