Airtel — poor signal and internet reception

Address:

Kothaguda circle,, Ranga Reddy, Andhra Pradesh, 500084

Dear Airtel,
I just moved in to a hostel where I can't even speak on phone properly for 5 minutes, I will have to haul the complete hostel or go to the terrace to talk on phone and i am writing this complaint on WiFi not on the 4g data that I paid for because not a single page gets loaded.
Please look into the issue.
