Airtel — insufficient internet speed provided by my sim card

Address:

Pune, Maharashtra

I am now using airtel services since last august (2017), but since my last recharge of 1.5 gb per day the net speed has attained a new low. The data never catches 4g signal, always runs on 3g signal and that too at the speed of 2g.
Being a college student i am in a constant need of high speed internet.
You (Airtel) claim yourself as the fastest internet service provider. But the situation makes it hard to believe you.
So please take necessary actions to improve my network speed,
Or i would rather have no other option than to change my service provider.
