Indigo Airlines — missed flight which was standing at airport and connected to escalators

Address:

Kanpur, Uttar Pradesh, 208011

For lucknow to bombay flight on 27 july 2017, flight no. 6e 685, i accept that me and 10 other passengers reached at airport late which was due to heavy jam on the kanpur - lko highway, however when we reached airport, the indigo staff issued the boarding pass to me and 2 more passengers and we immediately rushed to the boarding gate, but there was no communication between the issuing authority and the man standing at the final gate due to which the final entry gate person stopped us from entering in and spoke to us in very rude tone as if it was our fault for being late, and while all this we could see that the plane was still standing connected to the jet bridge. We kept requesting to him that the plane is still connected so please let us enter, but the man rudely rejected and after 10 min of his rejection the bridge was removed.

If it was a question of 1 or 2 persons i would have had noi say in this, but there was 10-15 passengers and the company still considered no one to let them enter the plane.
Specially the 3 o[censored]s who received the boarding pass from the counter and reached the final entry gate and still were not allowed.

It felt like the airlines was trying to sell the tickets of next flight as we had to reach bombay the same day.
We had to pay for next flight while the flight was still at the airport.
It was purely to sell 10-15 more tickets of next flight.
