GoAir — flight first delayed then cancelled, now no response from goair

My father was travelling from delhi to bagdogra. He was first informed that the flight is delayed. After waiting for 3 hrs, he gets to know its cancelled. Its been another one hr that he was said for the accomodation but no response, infact the go air staff are misbehaving with him. Is this the kind of behaviour with flights these days?
He has had to struggle with the airport authority and he is damn tired now. If this continues, i will make sure the complain reaches higher. I have some videos of the same.
