Desperately seeking Telkom service

Our land line is down, so ADSL does not work - no wifi/internet The Call centre logs a fault as says a technician will attend to the problem. A month later and not a technician in sight... We have called 4 times - and received 4 different answers to our problem: 1. Faulty line 2. Faulty router 3. Junction box problem in the street 4. ****** cables SO WHICH ONE IS IT? We have also been to the local Telkom customer care store and their response is that there is nothing they can do - please call the Call Centre. It really is a joke! Clearly the Call Centre operators don't really care about the problem either and they have NO solution just another excuse each time we call or visit. AND WE STILL RECEIVE A BILL EACH MONTH FOR ZERO SERVICE.
