Himachal Road Transport Corporation [HRTC] — misbehaviour of a bus conductor

My brother aged 15yrs is travelling in hrtc bus for the first time. The bus was scheduled to depart from gurgaon at 6:00 pm. The bus departed on the scheduled time but on arriving delhi, the bus stopped at delhi isbt for unreasonable time. On being asked for the reason behind this, the conductor spoke very rudely to the child and asked him to take another bus. My brother was really frightened by such behavior. My brother even asked for the bus no. And name of the conductor which he refused to tell. I request to you to kindly look into the matter as such kind of behavior towards the children is not tolerable. The bus was routed from gurgaon to baijnath. Departing time from gurgaon being 6:00 pm.
