Vistara Airlines — Denied boarding worst airlines

Address:

Dehradun, Uttarakhand, 248001

I was denied boarding for my vistara flight. My flight pnr for travel on 15th may is 5xbm5q. It was a kochi to delhi flight. Departure time was 5.35. I reached kochi airport at 05:00, 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. And also i suggest to all my colleague never travel with vistara, it is worst airline
