Union Bank Of India — for timing

When my father goes to union bank of india lolada branch (Taluka-sankheshwar, dist-patan, state-gujarat) 3:45 pm then branch's man said to the branch's time is over. He knew that the bank is open but your bank's behaviour is not good. I experienced 2-3 times that types of behaviour. My father did not go to raise money or deposit, only my grandfather died, he went to transfer money from his account. When the employee of the bank refused to come in my father's bank then his acquaintance let him come and let us go. It means that the bank is only a recognized entity. If my family has 6 accounts in unioun bank of india, can i close all the bank accounts due to such employees? Please request the bank manager and bank staff to comment on this matter. Is the time for the consumer to be between 10:30 am and 3:00 pm only?
