A week later and no answer

So, on the 31st of December our ADSL line just went dead. Phoned my service provider, checked things on their side, they reported back saying it was the line self(Telkom). So on the 1st of January I decided to phone them and report the fault, I was told that it would happen the same day or the next. So on the 2nd I phoned back asking what the progress is, I was then told that no one would come out because it was a public holiday, next day phoned again and got told it takes between 72 hours and 5 working days to get the problem reselved. Guess what... It's 5 working days, technically 6 since the fault was reported, and still nothing has happened. Phone the call center and it's the same old textbook answers. Nothing concrete, no one bothers to actually take action. How much longer will this go on? How will I get help out of them and get this issue resolved?
