Ola Cabs — Charges applied for stoping at traffic signals and traffic jams

Address:

Bangalore, Karnataka

The Complaint is with Respect to Excess fare charged in terms of waiting time.
I had booked the ola cab on 14th feb 2015 from katriguppe to yelahanka new town on phone.
Booking Date and time 14 Feb, 2015, 10:56 am
Pickup Date and time 14 Feb, 2015, 11:12 am
We Reached yelahanka at 1.21PM during the Journey we never made the driver to wait for our Personal Reasons There was Traffic singals and Traffic Jams as usual in Bangalore.
My Complaint is why i have to Bear the cost in terms of waiting time which is not due to my fault.I was neither informed when i booked the cab by their call center executive nor the driver about the waiting time charges.

This is clearly cheating on part of ola cabs charging excess fare in terms of waiting in traffic.how the waiting time is being calculated in their software and have their software been validated by any government agency?
