Himachal Road Transport Corporation [HRTC] — regarding mandi sakroa daugrai bus going earlier than its time

I want to address an issue regarding a local bus route which is Mandi Sakroa Dugrai bus.
First of all, it's the only bus on that Dugrai road and second its last bus for all persons living at Dugrai side. Considering this the bus should reach at its time in evening, because no source of public transportation is there after that. However, Dugrai bus goes earlier in the evening several time which is causing issue to the people of that area.
Also, bus provided in that route is not in very good condition.
Bus timing to cross baggi chowk is 5:20pm but it is going way before its timing i.e. 10-15 min earlier, which is making difficult to all people to catch the bus. So kindly resolve the matter earliest please.
