Airtel — poor signal — multiple complaints — poor response from airtel

Address:	Ranga Reddy, Andhra Pradesh, 500049
Website:	www.airtel.in

We are residing in raghavendra panchajanya, prashant nagar, near alwyn signal, miyapur, 500049, we have been experiencing very very poor signal
In our apartment premises, and many of our apartment neighbours around 200+ connection users also facing this issue. Our request simply put on hold claiming some approvals required to fix this issue for almost a year.
Even after raising multiple complaints they are simply closing the call by saying we need approvals. I don't understand airtel such a brand with high reputation couldn't able to fix this signal issue in the heart of the expanding city of hyderabad. Many of our apartment people also facing this issue.
I request airtel to take this with highest possible priority and fix the issue.
