Indigo Airlines — No show at Gate due to long queues in Security

Address: Chennai, Tamil Nadu

Indigo Flight 6E-976 @ 6:35 am on 2nd Feb 2017. Taken boarding pass well in time but was not allowed to travel as Security not cleared before fly-time. Flight actually left at 6.32 AM. More passengers missed the flight. No effort by Indigo staff while other airlines were pushing passengers to jump queue in security. IS Indigo earning extra revenue by this action? Again incorrect information was given- Staff at gate told by next flight I can travel. Manager informed that will get credit to missed flight.However reservation staff told to buy new ticket costing Rs 9790 and no credit on missed flight. I request refund of at least cost of missed flight @ Rs 5441.
