Indigo Airlines — Held at airport for no fault of ours

I and my husband were traveling from Hyderabad to Goa on 6E 744 on 6th Feb 2017. Our flight was scheduled to leave at 5:50 AM. We were at the airport 1 hr 15 minutes before departure and patiently waited for our turn at the check in que to get our boarding passes issued. All this while we could hear a lot of calls made out for passengers traveling to Ahmedabad to hurry up for boarding but none at all for Goa. We reach the counter at around 5:03 AM and while we were waiting for the guy at the counter, he was no the phone and after keeping the phone down he informs us that flight has been closed at 5:05 AM. It was the most absurd experience. When we talked to the manager Hari Vignesh, he curtly told us that we were late. LATE??? We were in the que and no announcement was made for Goa Passengers at all. After a lot of arguing and seeing our frustration the manager agreed to put us on the next available flight that was at around 1:10 PM the same day and we were put on that flight. Imagine our frustration :-
1. We get up at 3:30 AM, get ready, hurry up and reach 1 hr 15 minutes before the departure time only to be told that we are late when we were not
2. Our first day of vacation was spent waiting at the airport. By the time we reached Goa it was 3:00 PM.
3. The staff handled it very callously. We've always traveled by Indigo but don't think will be doing so in future. Despite telling your staff that they are diluting the brand they are working for, they were downright arrogant.

If you can put yourself in our shoes and understand that if one day of your vacation is eaten up because of airline staffs' fault, how would you feel?

We would request you to go through your CCTVs and verify the contents of this complaint.

We always had a great regard for your airlines and have been goodwill ambassadors of sorts recommending your airlines to our friends and family. But this one incident has shaken our confidence in an airline that we otherwise thought was most efficient in India.

We hope that you can compensate for the inconvenience caused to us.

Thanks
