ADSL unavailable for 4 weeks

Hi<br> <br> My adsl stopped working with the router flashing , Telkom called and they suggested the router needs replacing, Replaced router and it worked at the supplier. Telkom came out and are unable to fix the issue for 4 weeks now. They keep saying that its being looked at. No feedback, I have to call them daily. t took 5 phone calls to get an initial response from them. I desperately need the ADSL for work that Im doing
