Can't do our jobs without internet! Can't get Telkom to fix our line.

We have been trying to run a business without internet since the 17th of January. There was a storm on the 16th that knocked out our internet. We know from over 20 years on the property the problem is at the back of the premises where the ADSL line is connected to the pole. We unplug everything every day when we leave so we know the problem isn't with the router. We've logged the fault with Telkom (at least 6 times and got 3 different ref. numbers because they keep closing the fault) and every time we call they tell us it's been resolved (when it hasn't). Their technicians keep going to the exchange even after we've requested numerous times that they come to the premises as we believe the problem is here. We can't run a business without internet so this is unacceptable. We always hear they're escalating the fault so we will get help but nothing has happened in almost 2 weeks.
