Hlw sir,
I am leaving in Bhagalpur . Here speed of jio is very slow these days like on 29 and 30 October.
Taking big amount for recharges and not providing the speed 4G.
They are just looting money from us . Even when we call customer care executives no one is there to answer the call.As I have screenshot the record of speed through fast.com which gives the speed 550kbs. as a average speed which means 69 KBS approx. Which is not even a 2G speed inspite of having 4G full network
