BSNL — very noise in my bsnl landline connection

Address:

near DC office Rajouri, 185131

I stay in rajouri district near dc office office rajouri, where exchange is just a few metres away from my residence
And i m facing this noise problem from a very long time. I use to complaint with local bsnl exchange office, but they dont take it seriously.
Not a single time a person from tecnical background with some tecnical knowledge came to see my problem, only a lineman come sometime, drink juice and go away with saying that all i m here to just confirm dialer tone.
Strange... An exchange which is just a two pole away from my house cant rectify my problem.
Exchange is just a 300 mts away from my residence and still they are
Careless about my problem.
I am fed up with their service as i couldnt make a call because of so much noise, i have also opted for broadband but connection keeps on breaking and when it connects i get very low speed... Very low than the bandwidth for which i m paying.
Please take some action. Otherwise we have no other option except throwing out this showpiece telephone
