Ola Cabs — Pre booked, cab cancellation done with no warning

Hi
Had pre booked an early morning cab to the airport, about 12 hours before. Got the booking number immediately, just to be sure, I called up ola support about 8 hours earlier, to check if they would indeed send the cab at the scheduled time of the morning. They assured me they would do that. 15 minutes before the scheduled time, I hadn't received the cab details yet..I therefore called up Ola support wanting to know the cab details... And then they inform me that the cab is cancelled ... And ask me to book another cab in the Ride Now option, which is completely unreasonable that early in the morning . Ola cabs should not be taking pre bookings if they cannot send a cab at the appointed time. Extremely disappointed and frustrated with Ola cabs
