Vodacom - Can't port number, Suddenly my number does not exist.

Worst service ever, I've now been trying to port my number for 3 weeks, phone the porting department 3 times and waited more than 2 weeks and no resolution. The worst is after the port request that vodacom decline my number suddenly stopped working and now says the number does not exist so I cannot even use my old vodacom sim to receive calls. When you call the call center they just say they will log a call and you have to wait a few more days. They never even send the reference number that they say they will send. This is really the worst service ever
