Telpehone service out for a week

Out telephone line frequently goes down, and this time it went down a week ago. There fault track doesn't give proper feedback and nobody contacts you. Then a message comes in saying fault resolved but in fact it has not been and then one needs to log a new fault and start over again. Phoning 10210 doesn't help as you hold on forever and phoning from a mobile phone one cannot afford to hold on indefinitely.
