Taking forever to react & repair a fault

I have had a continuous problem with my ADSL line since middle of last year. As of the latest fault reported, it STILL has not been allocated to anyone, and the ADSL remains off. Apparently you are aware that there is a cable problem, but why does it take so long to get the offending cable replaced? My router wont sync, when it eventually does, it drops again after a few seconds. Now it wont sync at all. The telephone line crackles like crazy, every time it rains, nothing works and nobody is really interested to come and check each connection in the cable. When will my service be restored properly and permanently?
