Airtel — unable to receive calls and sms in 4g network

Address:

Bangalore, Karnataka

From past 3 weeks i am unable to receive any incoming calls and sms whenever i turn on 4g.. But the same problem is not faced if i switch to 2g.
This is very annoying as i am missing out on very important calls and iam not able to make any otp related payments. The issue is faced by many people in this area.

My address is global village back gate, rajarajeshwari nagar, bangalore.
