Ola Cabs — False confirmation for sending the cab: Missed the flight, Communication befor elegal notice for damage done

Hello, This is with regard to CRN 99709531 booking confirmation with following details. Booking time 07:52 PM, 12 Jul 2015 Pickup time 03:45 AM, 13 Jul 2015 Pickup address :Saarrthi Sovereign Hinjewadi Rajiv Gandhi Infotech Park Pimpri-Chinchwad Maharashtra India This is an intimation before i send a legal notice for the economical damage done by OLA cabs by falsely confirming the Cab booking. When driver was approached, 20 minutes prior to the pickup time ( 3:25AM), his number was switched off. I tried calling customer care which was unreachable. I missed my flight because of this. As it was very early in the morning, I could not get any other cab. I have my flight tickets to show and the proof that i could not board the flight. I have recording of both the failed attempts to reach OLA (driver and customer care). Please provide the explanation as early as possible.
