Dot Cabs India — non compliance of the confirmed booking

I have booked innova on 15/08/19 to drop off to the airport on 16/08/19 @ 11:30am. My booking has been confirmed by the call center agent and got confirmation booking sms as well and said that will get driver details 30mins before dept. On 16/08/19 @ 11:05am dot cab, hyd supervisor and said unable to provide requested vehicle and they are cancelling the booking and this is completely unacceptable and found very much difficultyb in getting alternate vehicle and we suffered a lot and we are about miss our flight, reached very neck of the moment and was the last passenger to check-in. This is second time happened with me and completely unacceptable this sort of negligence and due to this we suffered a lot twice. I would like to take legal action on dot cabs, hyderabad for this sort of negligence and unprofessional approach..
