Uber India — Non availability at airport

Address:

Kolkata, West Bengal, 700027

When I can see at least 3 cars near domestic terminal on 21.02.2016 at 14.10 hrs, & they are not moving but available, still uber didn't take my request, which lead me to book an ac car with Rs 890, when uber ride is only around Rs 300 for the distance. I am going to lodge a complain in consumer forum for this irresponsible behaviour. Please furnish your explanation. As my senior citizen parents also suffered for this behaviour.
