Himachal Road Transport Corporation [HRTC] — traveling inconvenience in hhrtc bus when rain water came inside from closed windows and wetted me

While traveling on apr 8 2018 at route bilaspur to katra. I booked seat no. 19, bus no. Hp 69a 1464 from bilaspur to jammu. During traveling in bus after (Mid midnight) near pathankot at around 1:30am while i was sleeping in bus at my seat suddenly water came inside, i was shocked all my cloths were wetted. I saw it was raining out side and rain water was flowing inside even all windows were closed. Passengers behind me were also standing due to water coming at their seats also. Since all seats were occupied we traveled our rest of journey to jammu by sitting on wetted seats and intermittently standing.
