Beware with some drivers with payment I had some experience like this. I booked cab for my wife where she coming back to home.
It around 16km in Bangalore when she reached the drivers said amount Billed Rs.680 where usually it will be Rs500 when we gave him 700 he took that cash and also he deducted the amount from ola wallet Rs 500. Even when you need cab urgent like rainy time they will wont come even the cab booked. I faced this kind of issues 2 to 3 times.
