Indigo Airlines — worst, non, supportive they should not be from hospitality industry. indian gov. should cancel there registration

Address: Kolkata, West Bengal

How come a airline run without any manner or behavior in civilized industry? I suppose to travel from kolkata to guwahati on 26th sept. Our flight time was 6.50 am. When we reach indigo counter at 6. Am, the indigo representative said that counter already close and flight already full. And the so call airport manager also was very roughly behaves, like never worked in professional way. Indian gov should ban this kind of airlines.

Flight no - 6e623,
Baggage checking time 6.05am (Although we reach 6.00am)
From kolkata to guwahati

Even i will never travel this stupid airlines. I travel a lot in domestic and international flights. But this is like a nightmare.
I don't no how much action will take by the company but i will suggest everyone don't travel with indigo airlines.
