Ola Cabs / Ani Technologies — extra fare charged after the ride

I had booked ola auto on 03 feb 18 at 09:18 pm by auto crn [protected] from wanowrie police chowki to shredded lodge in pune which is around seven kilometers, fare shown at the time of booking was rs 59 but after the ride fare came out to be rs 72. I told same to the driver and he said that the fare was system generated, and it is correct. Please check and refund the amount charged extra.
