Ola Cabs / Ani Technologies — driver came late and even charged rs.40 extra

This is to inform that we had booked a ride on 8th march 2018 (Time:at 5:00 am) and driver didn't reached to our home till 5:20 am. So we called up to check where was he.
He didn't knew the location we had given. And was roaming around.
We walked around 2 km with our big bags in our hand and ran as we had to catch the train. And distance to be covered was 12 km, which would take around 35 min time.
Somehow we caught him on the road and when we reached the railway station.

The total ride fare was rs.156. But he charged us rs.200.
Instead of his fault he blamed us for nothing.

And this is not one incident.
Before few months ago, we booked ride from airport to home.
So the driver charged us the extra airport charges. (Rs.80 extra)

Request the ola cab company to look into this issue.
And instruct all drivers to charge only what is approved by the app.
