Ola Cabs — cancelled my cab booking on their own

Address:

Pune, Maharashtra

I had booked cab for 10:30 PM for 20-Feb-15. Booking id CRN62057534. I did not receive any communication on cab and driver details. When i called at 10:30 they told me cab is just 5 min away. I called again after 5 min, they told cab is reaching. Again i called and to my shock, they told my booking is cancelled ! Then they took my new booking and sent another cab at 11. I could have missed my flight. This is totally unprofessional. Other consumers, please be aware of this stupid Service
