Airtel — network issue is not resolving after several complaints

Address:

560036

I am having 4 airtel numbers. All numbers have same network issue.

I called several time to customer care. But they are just giving promises to resolve the complain within 2 days. Around 20 days happens but no resolution.

This issue is in t c palya bangaluru. I need solution not their false promises.

Recently i have ported my number so till 3 month i can't port it to other vendor as well.
