Uber India — overcharging for the trip especially when on ride pass

The uber is charging hefty amounts on the grounds of the gps route not followed.in one of the cases, uber charged me rs. 147 & rs.132 (Ride on 23.01.18 and 19.01.18) where as it should have only charged rs.89 and in another case on 06.03.18, 9.03.18 & 21.03.18, it charges amounts between 100 to 150 citing the same reasons. You can only chat with the uber and you get standard reply from their chat bots for issue resolution. It seems the initial map at the time of trip booking is going pathetically wrong to calculate the best route and their is no comparison provided for which they are charging high. Legally, they must provide the proof for higher charging.
