Airtel — not responding to my request

Respected sir,
Im living in a village where there are more than 7500+ peoples are using mobile phones with airtel sim connection. But we don't have clear 3g and 2g network in our area. I have complained about the issue with 'airtel open network' even with 'airtel appellete authority' but no one responding or giving proper solution to my problem.
Im complaining about the problem since last 6 months but my problem is still pending
