Ola Cabs — Incorrect waiting time shown on app

Address:	Mumbai City, Maharashtra, 400061
Website:	www.olacabs.org.in

I have been forced to cancel multiple Bookings in the past 5 days for the following reasons:
1. Cab distance shows as 2 mins away but after booking the waiting time changes to 10 mins.
2. Driver can't read GPS to locate my position
3. App cannot locate my position, it shows previous location as pick up point and I have to manually type in my present location, otherwise cab is misdirected
4. Sometimes as happened today (April 18, 2016) two Cabs got booked at the same time. I booked one at 9, received a message with cab details, and then when cab was delayed at 9:15 I got another message with booking details of another cab with different number plate headed for me... Total chaos!
