Airtel — very poor network service

Address:

New Delhi, Delhi, 110059

I am airtel network user from new delhi and having 6 connection of airtel no. (Prepaid and post paid both), currently from last 1 month network condition of airtel is very pathetic and bad, i also lounge a complaint on airtel portal about this from the number ([protected]) but no any action taken from company side, we are even not able to receive any call from anyone due to network issue, after we are getting msg alert for missed call, then we came to know that some one is calling, internet connectivity so poor even in 4g speed,
We are very much upset and frustrated because of this, because in current scenario mobile is a part of life and it create a problem in our day to day routine job.
Pls rectify it otherwise we have to switch some other network.
