Trai — Network issue in our housing society

Address:

Airtel Thane

Dear Sir,

we are the residents of Cloverdale, One Hiranandani Park, Patlipada location. Since last 5 months we have been approaching all cell phone service providers to improve the signal strength so that we can use phone for receiving and making calls smoothly. Most of the time person on the other end is unable to hear our voice properly. Many complaints were raised to Airtel, Vodafone, Reliance but not relief. I am airtel user, whenever I try to lodge complaint in their app it doesn't accept only.
please look into this matter urgently and advice all companies
