Beware of some drivers with payment I had some experience like this.
I booked cab for my wife when she was coming back home, it was around 16km in Bangalore when she reached the driver said Bill is Rs.680 where usually it comes to R s500.
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 urgently like rainy time they will not come even if the cab booked. I faced this kind of issues 2 to 3 times.
