Himachal Road Transport Corporation [HRTC] — Balance not returned

Address:

Paonta sahib district sirmaur 173029

I'm traveling through and HRTC bus no.
HP18B 6537

From cahndigarh to Paonta sahib
I collect ticket from counter and given 300 to the collection man, the ticket was of 228 but he didn't return anything back after asking for 30 re change and which i didn't have. He refused to give balance money at the moment and gave ticket to mw after mentioned my seat number on it. I thought he will definitely return money after the bus will depart.

At the time bus depart and i talked to the other conductor who was there in bus after bus departs he told me that he can't return the money's as it's got debited from that first collectors machine.

I don't know who's wrong here but it's an failure or miss communication from the department. Kindly check the matter and resolve the issu.
Depart time - 7:25 PM cahndigarh sector 43 bustand
My balance is 72 Rs.
