porting nightmare from 8ta to Vodacom

i want to port my number from 8ta to vodacom as i do not have internet signal when i am at work. i went to two different vodacom stores to port and the verification messages do not get delivred to my 8ta number. i called the 8ta call centre and i was told that they are aware of this and there is nothing they can do from thier side as the problem is on vodacom's side. The call center agent said there was an incident logged and she refused to give me an incident number and also refused to give me contact details of the technical person dealing with this query as \it is against company policy". i need someone from 8ta to explain why the porting verification messages are blocked!"""
