Unable to receive calls from other users.

Once again the same problem. Unable to receive calls. After losing business and customers' frustration about not getting hold of me, it took Vodacom almost 2 weeks to resolve the issue. Now a month later the same issue again, unable to receive calls from Vodacom. The first consultant promised to log a ticket, like most consultants, never do. The second one, wanted me to unblock numbers etc which again is not the issue. Now I have to fight and call 100's of times before I get my voice heard that this is a Vodacom system problem. Is this going to happen every time my contact upgrades / migrates or something similar?

Now I have to wait 3 business days for a response, then basic ID10T troubleshooting trying to prove that the customer is at fault, and hopefully after one week get through to an engineer and then another week of troubleshooting before a resolution. In the meantime, my customers think I am unreachable and out of business and calls someone else?
