Airtel — low 4g data speed

Address: Gulbarga, Karnataka

As u guys claim airtel is the fastest data provider in india, but even if i switch on 4g the data speed is too poor, i cannot even browse or stream youtube videos, server is lost frequently while playing games such as pubg, if this continues i'm gonna switch to some another network, i had been using airtel since a long time, but it's service has become poor day by day,
