No service 7 days after porting from MTN

I \moved' from MTN to Vodacom on 3 March and still do not have full service i.e. can't receive calls, sms's, e mails. The Fourwys Mall brach has escalated this 5 times on my behalf and I have contacted the call centre 6 times, aslo sent e mails to Vodacom. No one seems able or willing to assit me. I use this phone for business and this is clearly a huge problem. I am at a loss, I cant go back to MTN for 3 months or I would do it is a haert beat!. Maybe someone can assit but I am not holding my breath, Vodacom have been pathetic!"
