Useless Vodacom!!! Cannot recieve calls from some networks

I did a number port from fnb connect to what is supposedly the leading network in SA, Vodacom. I was sadly mistaken. Since my vodacom sim became active I have been unable to recieve calls or sms's from cellc/fnb connect. It seems to be working for mtn, vodacom and telkom. Calling the call centre just results in dropped calls or people who actually have no idea what the problem is. I had to resort to google and find that it is a problem with the routing. Someone called me and said it was resolved but it has not and now it seems they have no idea what could be the issue. Ive tried all methods of communication but no one is able to assist me. Extremely terrible service and I wish I never ported. This will also likely fall to deaf ears!
