GoAir — delay of flight g8 424 hyderabad to delhi

I am flying on the above mentioned flight on 18/02/18 flight was scheduled to depart at 10:40 and now rescheduled to 13:10 hours. The staff is unable to provide any further details regarding the cause of delay or any more delay expected. This is highly unprofessional behaviour on part of the airlines as people choose a particular time of travel for n number of reasons.
