Telephone line and ADSL line dead

My telephone line went faulty on 23rd of December, fault logged on 24th. Technician came and had a look and could do nothing, another technician was sen on 29th, fault not corrected and technician left. I called the call centre again, and the fault was escalated. I was away until the 8th, when a further fault was logged, no technicians have been to check on the fault and I have called the call centre every day, and every day they say they are escalating the fault. Very frustrating, as there is no complaints division and no higher level than the call centre. When I try to log a further fault, the system will not let me as there is a fault in progress. Any idea on what steps I can take to try to get this resolved. I am paying for a line that I cannot use, I am also paying for an internet service that I cannot use and I am using my mobile phone and increasing the fees on that.
