Air India Express — Very poor service from Airport staff

IX 813 Mangalore to Dubai 27th March 2022.
Passengers waiting in the airport from 5pm and flight is to leave at 7.55pm. The flight is delayed, there is no intimation of the delay and people have to just wait looking at the display board. Its passed 8 hrs waiting in the departure lounge and still no support from Air India Express staff.
The staff at the airport have no clue when the delay will sorted or offer no support to the passengers.
What a pathetic situation.
Your duty manager has to be fired for his incompetency to mange his work.
Very very poor service.
