Uber India — I was overcharged

Website:

I have booked a uber pool ride on 27th june at 6:41 pm which showed the estimated cash fare of 40/- and during the trip my driver stopped the car due to internet interruption in his mobile. I have helped him to begin the trip in his mobile by offering hotspot. He has started the trip and after reaching the destination the fare showed was 127rs. How come it would be triple the amount in the uber pool ride for the same distance? I have written to uber help but none have responded till now. So thought of complaining here.
