Uber India — over-charge for trip

Address:

Gurgaon, Haryana

On september 9, 2017, i booked uber pool from sapphire mall, sohna road, gurgaon to huda city centre metro; cost shown was rs. 59. That is the cost everytime i book a pool on the same route. However, i was charged rs. 153 at the end of the trip. A passenger who sat before me dropped-off midway and did not pay anything. I ended up paying for him and me due to the driver's fault of either not ending that passenger's trip or starting mine before i sat.
Note that there was normal traffic and the cab did not go off-route once i boarded the cab.
I need a refund for the extra amount charged.
