Ola — Charged incorrectly for extra distance and toll

Booked Ola outstation in the morning from Gurgaon to Bareilly for my parents. The fare showing to us was 2776 excluding toll but final bill came out to be 5519including toll . Toll charges in this route is not more than 700 but driver took us 1060. Ola added extra km charges also in the total bill which is unfare. Bareilly to Gurgaon distance is only 290 km. My parents and driver both agreed that they didn’t travelled any extra km.
Tried calling Ola customer care but they are marking issue as resolved.
