Land line Telephone not working

I have been paying my telephone and broadband bills without any complaint and break. But, my phone has been out of order for last three (3) months. I have been getting telephonic complaints numbers, but nobody comes to put my phone in order. It is still not working and I haven't phone for last three 3 months.

Could some good and sincere authority help me. My phone number is 220178 stationed at Lal Lake, Dharamsala, H.P.
