Union Bank Of India — improper behavior while submitting request for loan account closure

Address: Mumbai City, Maharashtra

I visited the Kandivali east branch for Union loan point on 28th July 20017 and had to face a severe behavior issue with customer service representative over there.
My Father visited the branch at 1:15 pm and asked them to check my loan account ([protected]) for which i was supposed to do a pre-closure for buying a new house.
The customer service representative named "Yogesh" asked my father to wait for some time as he could not see the amount of pending principal being transfered in my UBI account from which EMI is getting debitted.
The representative went for a lunch break. I arrived at the branch at 2:10pm and as per my fathers discussion confirmed with the UBI home branch that the necessary amount is already transferred in my account.
The representative came back around 2:55pm and me and my father went to his desk as our processing was left in between.
While the representative was away for lunch, 5-6 new customers arrived at the branch and even they approached him.
Instead of conducting a first come first serve approach he started attending his known customers.
I questioned his approach and that my father has been waiting for more than 1:30 hours, to which he replied that he knows his work and this is how it is done.
I told him that my processing was left in between and all required amount is already transferred in the UBI account. He was only required to process the pre-closure request.
He further insisted with a raising voice that the bankers dont require teaching from the customers on how BAU is to be managed.
I was upset and asked for an escalation contact to which he responded " you can approach any one but your work will be done as i want".
I have been UBI customer since 9 years and have never come accross such arrogant customer service, especially because my father who ages 56 was made to wait for 1:30 hours.
I did raise a grievance request on the UBI site under :[protected], but there has been no response till date.

Really appreciate if this matter is taken seriously by appropriate authorities as we expect at least basic customer service norms to be followed while attending customers.
