Indigo Airlines — i missed my flight from delhi airport to kochi on 21/11/2017 in spite of arriving more than an hour in advance

I missed my flight from delhi to cochin yesterday, nov 21, 2017 trip id [protected]. When i arrived, i found one long queue for flights to different destinations. Even the counters to different destinations were not specified. There was an airline staff stationed there just to watch over the queue. When i reached the counter, i was asked to rush to another counter with my baggage. When i reached, they said the gates were closed and i couldn't travel. When i asked they why there was no announcement for those who were delayed to hurry, the answer was that delhi airport is a silent one! I didn't get a refund nor booking for the next flight. There were other passengers like me bound for kochi, mumbai etc who faced the same predicament.
