Airtel — airtel network issue at b. p. road, bhayander east

Address: Thane, Maharashtra, 401105

I had complained to airtel regarding continuous network issue at b. P. Road, kharigaon, bhayander east.
They are aware that issues are there but they are not willing to invest in improvement and let go customers if they want.
So please take this matter seriously otherwise i have method to port my number to any other good network company in our area.
