PORTING OF CELL NUMBER

My husband took out a Vodacom cellphone contract for me on 7 March 2016 and it was agreed that I would port my existing cellphone number to the Vodacom network. I received an sms from Vodacom on 23 March 2016 at 9.30am saying that the porting of my cellphone number had been approved. It is now 8 days later and my cellphone number still has not been ported. The contract was taken out at a Vodacom 4U outlet and I have been phoning them every day to find out what is happening with the porting and they cannot give me any answers. Vodacom 4U are insistent that they did everything from their side and that the problem lies with Vodacom. I cannot find anyone at Vodacom to speak to about my complaint and Vodacom 4U cannot find anyone at Vodacom to speak to either. I don't know what to do anymore as I now do not have an active cellphone contract. It is absolutely ridiculous that I have been waiting for more than 1 week for Vodacom to activate the porting of my number and that nothing seems to be happening.
