Telkom Business ADSL line down for 15 days and Telkom does not care

Business ADSL Line Been unable to operate online store for 14 days Telkom does not care After 5 days of fighting a technician arrived, told me my modem is to old as the exchange has been upgraded, swears on his life that a new modem will fix all. I buy a new modem and install it, SUPRISE, still not working After another 2 days of fighting a new technician arrives, he says he is from high level support, he messes around for an hour and says he knows what the problem is, makes a call, tell us not to worry, his capable hands will resolve it for us ASAP That was 5 days ago, never seen him again, now for the last 2 days Telkom says that they are waiting for a technician to become available so they can send someone out WAIT, what happened to the previous one Is no one held accountable for NOT doing there job?

How do I get my Internet fixed???????
