United Bank Of India [UBI] — money debited from my account instead of any withdraw

At the time of 18.56 pm when i was trying to withdraw money from pnb branch atm but money debited from my account without any kind of withdraw. And i got a slip where mentioned that "sorry for inconvenience incorrect pin" but clicked correct pin no within confidence.
Sir plz cooperate to get back full amount of money which was debited yesterday.
Hopping to be favoured for your compassionate consideration.
Thanking you sir.
