Ola Cabs / Ani Technologies — ola charges rs 150 extra as parking charge at the airport pickup.

Address:

Faridabad, Haryana, 121003

I booked the Ola sharing cab from Terminal 3 IGI airport. During booking it shows the charge as RS 632 . But driver force us to pay rs 150 extra as parking charge which leads me to pay rs 782 .
After making payment of RS 782 total but in app is show the payment of RS 632 only. My concern is why the driver charges the customer 150 extra. If he charge it must be added in final payment and must show in app that i paid 782 cash.
