Porting Numbers, incorrect information supp****

Essentially, I had a Virgin Mobile Prepaid number. I wished to take out a Vodacom contract, and port the Virgin number across. I followed the instructions I was given completely (and have voice recordings of the relevant calls) only to find out that the instructions were incorrect. I therefore had a new activated contract number. I have subsequently been told that the only way to rectify the situation is to cancel this contract, and start again. While this is ridiculous (it is Vodacom's fault) I am willing to do this. However, I am still waiting for the call back from 'higher up' to go through this process with me. It is more than a month later. Vodacom, please just change my number to my old one. And don't you dare charge me extra because of your mistakes.
