Indigo Airlines — Flight missed need refund thanks

Address:

Kolkata, West Bengal, 700028

I missed my fight on 14 nov from kolkata to Raipur due to boarding counter rush. My Pnr no was M7ZEPC. I need my money return.It was not m fault, i was standing on a line to get a boarding pass but there was a long line of passenger still waiting to get there boarding pass and i got late by 10 min. after that a lady came to me of indigo airlines and take me to an another counter of indigo. Then i showed my print copy to the counter person and suddenly she told me that boarding counter is closed. this all happened with me on that day and put me down very badly. Boarding counter was closed by only 10 min than why didn't they provide me my boarding pass. that was so annoying for me at that moment .
