Number port not happening

I have been trying to port my number from Telkom to Vodacom since 25 March. I have visited Vodacom in the Waterfront 4 times, Vodacom at Canal Walk once and the Cellucity Vodacom at Cavendish once. Cavendish were the only ones who were at all helpful but couldn't do the port becuase they didn't have the reference number for the sim I bought from the waterfront, as they kept it. Vodacom at waterfront actually sold me the sim card over a week ago and told me I wouldn't have to come in again, that the port would be done. I am still waiting. I have tried to call them over and over but they don't answer, their voice mail boxes are full, and if you actually get through they tell me the person who needs to help me is busy and will call me back, and never does. I am buying teeny tiny bundles of data from Telkom every day which costs me more, because I don't know when this port is going to happen. I can't believe I have to go through such a pain in order to give THEM business! I am not even a customer yet and I am already regretting it.
