Ola Cabs / Ani Technologies — overcharging for ola rental

I booked an ola rental cab in gurgaon for 2 hours / 20 kms.
We used the cab for traveling exactly 20 kms over 2 hours and 10 mins. However, i was shocked to see the final bill of 33 kms.

We traveled from point a to point b, stopped at point b for 1 hour and then traveled to point c (Total distance of 20 kms). To my surprise later, the driver drove for 13 kms at liberty during this 1 hour stop (Possibly ferrying other passengers for extra money), and even crossed a toll point of rs 100.
Even after reporting to ola immediately, no response has been received from ola for over 5 days!
