Airtel — not resolving network issue

Address:

500040

I have airtel network issue and even after complaining from past 1 and a half year no resolution yet. I have keep on following up on them. Even after tweeting only one response i receive that i should wait work is in progress. From past 1 and half year work is in progress. I need a strong action against airtel. When someone calls me when i am at home they get a response saying that my mobile is switched off. And i get a 2g internet at my home. I have to go out and use if i need to use internet.
