Airtel — worst network in marathahalli bangalore

Address:

560037

The signal for airtel is very poor in our area and we are facing a lot of problem while attending important calls. I am unable to hear others properly on call nor do others hear me.
Signal bar shows only one line. Voice breaks while on the call. Facing this issue from almost 2 years. The experience we have with airtel is pathetic and we have many airtel sims at our home.
Need resolution for this
