Cannot receive calls to my Business line for over a week.

I ported to Telkom Business Mobile about a month ago. For the first week, I could not receive calls or sms's although I could make calls and send an sms. It took a few days for the technical department to run the port again and all was good.. until the weekend. The number can no longer receive calls. I have called Telkom everyday since Monday and have been told every day that they are working on it but I receive no feedback. I have been promised that the agent assigned to the fault will call me, I have not received a single call. I have been promised that the call has been escalated and that a manger will call me.. Still no call. We are trying to run a business and cannot receive calls. Do not use Telkom mobile if you are trying to run a business.
