Horrible service and untrustworthy describe them aptly. The last time I had booked a cab was on the morning of that unfortunate day when Bangalore bomb blasts occurred. My booking was at 5:00PM and till 4:45PM the person from Meru cabs was telling me that the booking is confirmed and I will receive a call from the driver. Well, that did not happen and at 5:30PM when I was finally able to get across to them the person from Meru cabs told me that all their systems have crashed and all the cab bookings have been cancelled! I was genuinely pissed off but let it go considering what was happening in the city.
Today again something similar happened. I booked at cab to take me from the Outer Ring Road Area to Infantry road at 9:00AM. At 8:50AM I receive a call from Meru telling me that due to heavy traffic jam this booking is cancelled. Talk about reliability!
My experience with Easy Cabs and some local cab persons has been far better. At least they tell you clearly what can and cannot be done. With Meru you just do not know when your confirmed booking converts into cancellation. I agree with another review that they seem to be most interested in taking you to the Airport as that is where they make most money. Nothing wrong with that, but at least do not take bookings on other routes if you cannot supply cabs.
Will never book with them again.
