Airtel — poor mobile network worst

Address:

New Delhi, Delhi, 110087

Airtel has the worst network.in my home my phone always shows no service. Most of the time my number is not reachable. I have to use whatsapp calling, its much better than airtel.
Now these days while calling my number it most of the time shows user busy even while i m not using my phone. The problem is not only with my number.in my family we have 7airtel connections, all are facing network issues. We have airtel connectios for more than 10years, i think we have to switch to other network. I have complained to customer care many times, but the issue has not been resolved
