Ola Cabs — Cab booking cancelled without prior notice.

Address:	Hyderabad, Andhra Pradesh, 500032

I had made a booking for my brother with OLA cabs on 12th Feb 2016 evening for 13th Feb 4:15 AM for boarding a flight from RGI Airport Hyderabad, I got the confirmation for same. On 13th Feb at 3:50 AM I got cab and driver details but 10 minutes later I got a cancellation SMS.
I requested OLA customer care to provide me an alternative but all they could do is said sorry. I tried hiring another cab but could not get one in time and by the time we reached RGI Airport my brother was late & he could not board the flight. He had to buy another ticket in different flight that cost him another 13K.
