Spice Jet Airlines — Preporn of flight sg 280 without any prior information

Address:	Varanasi, Uttar Pradesh, 221010
Website:	Spicejet

I have a booking in spicejet sg 280 as pnr - v86i4z from vns to del.
Flight was preponed and i was not informed. I reached the airport at usual time but the boarding counter was closed. No one was there to help it out. When i further inquired, 3 more persons have the same problem. The station master mr rakesh didn't show any response and told clearance is not done by captain.in fact the flight take off after 25 minutes of all the incident happened. We continuously forced him to adjust us but it didn't go off.

How such an ambiguity is possible in airlines.
It's not expected.
The customer satisfaction is neglible.
If any preponement has to be done, customers should be prior informed via proper call.
The whole day wasted off on going to airport.
It's not accepted at all.
In fact i will not recommend any of my friend in future to board spicejet flight.
I want the compensation which is but obvious.
Plus improve the basic amenities which should be provided to customer by default.
Do the needful asap.
