Air Asia — boarding at hyderabad airport

I am having a flight to indore from hyderabad at 7:30 in the early morning. Being a college student i have to leave my campus according to some specific college rules. So i reach the hyderabad airport at 3 in the night.
There is no one at the air asia counter for boarding pass and neither there is someone to inform that the counter starts at so and so time.
If the airline is not able to hire employees then please don't run over early morning flights as many passengers come a night before due to some circumstances.
Why am i supposed to wait outside even having a premium lounge access? It's like 2 and half hours for the flight and the boarding hasn't started!
Very much disappointed service provided by the airline!
