Telkom worst nightmare!

Been having problems with the internet not connecting to the router since November. Countless fault reports have been logged just for them to say its fixed and me having to report it all over again. Just phoned now again and AGAIN was said problem was fixed bur still no internet. Router everything on my side is in perfect order. When they test the line even they say its a line problem. I am losing money daily since its a business. I really dont know what more to do. Client service are just really non existent. But still I need to keep paying for a service not delivered.
