Airtel — airtel 4g network is too, slow not even 1 mbps properly

Hi,

Im facing to slow network in airtel so called 4g, its worst than my old docomo 2g. Even many times call gets disconnected due to no network.
Fyi, this issue i am facing in bengaluru city not out skirts.

I m not able to do any single transactions properly using this network, it gets disconnected. Im trying since half an hour to raise this complaint, network getting diaconnected.
