Vistara Airlines — Denied boarding

Address:	New Delhi, Delhi, 110001
Website:	AirVistara.com

I was denied boarding for my vistara flight. My flight pnr for travel on 11 may is W3B38P. It was a Delhi to Srinagar flight. Departure time was 16:05 . I reached igi airport T3 airport at 15:20 (45 minutes before departure time), but I was denied boarding.
The staff was very rude. I cried and wept in front of them for half an hour but no one listened.
I will NEVER travel in vistara again.
