Be careful, if you are booking a MERU Cab.
I booked the MERU cab from Domlur to Majestic Railway Station with departure at 2:00 AM on 5th of Sept 2011. I booked it before 18 hrs from the time of departure. I called them twice to get the status of my booking. Every time they told me they can confirm me 20 minutes prior to the pickup time. Finally at around 10:30 PM at night, 4th Sept 2011, they called me and told "Your booking is cancelled due to non-availability of cabs". I had to go to the railway station with my family. It was a very difficult situation, I could not understand what to do at the last minute. Then I called JUSTDIAL, I got some cab service details and booked one cab and reached the station in time. My advice to all of you, If you are booking the cab through MERU and if it is at night, try to arrange some alternatives.
At the last minute they will tell "Sorry no cabs are available".
