Spice Jet Airlines — flight delay without any valid reason

I am waiting here after boarding the flight in spicejet, my flight number is sg 263, the schedule departure was at 5’55 am but now it’s 6’ 55 am and we have boarded the flight waiting for take off.
We have been given reason as some passengers from international connecting flight will be boarding this flight. The international flight is late
This is unacceptable, we have paid for this flight and the price of the tickets were also high.
After paying rs 18000 for 2 tickets now we are stuck in the flight.
On top of that the behavior of the crew members is awfully nasty. They are using slangs and if asked or enquired about the status of the flight they are threatening the passengers to throw them out of the flight.
