GoAir — attitude staff

Go air,
Me along with my family were suppose to board in flight go air flight on 30th december, 2017 from chennai to hyderabad. The flight departure time was 8:20 pm but we got a message stating the flight will depart after two hours due to "out of control" situation.
After reaching to the airport we came to know that flight will depart at 12:10 am on 31st december, 2017.
Passengers were really getting irritated while waiting there & go air senior staff was trying his level best to console us. But their junior staff miss. Dora maria from go air, chennai airport was carrying so much attitude that when a senior citizen asked her the reason of keep on delaying the flight she replied that due to fog in kolkata the flight didn't take off & immediately her following statement was "if you have any problem, you can complaint against go air".
She was very disrespectful towards that senior citizen & entire passengers. We passenger need to be given answers for a flight delay. We have not been sponsored by go air. We have paid for our travel tickets & flight delayed for 4 hours.
We need support from the staff not attitude!! Miss. Dora maria, keep your attitude at home.
