Bangalore Development Authority [Bda] — BDA complex 1st stage 2nd block HBR layout

I had visited BDA complex hbr layout 2nd block, where we went to a lady staff who was sitting in a adhaar enrollment section, to enquire instead of she responding to us in a. Correct manner she behaved very rudely in telling that she don't know about it, even though she did not know on it she could have told us in a polite manner but she behaved like a illeterate and uncultured women and kept shouting at us, this is not the manner to speak to public, when we as an educated are facing this issues then please think about the uneducated or ellderly people who go and ask for something and also she told you can go and complaint anywhere and nothing will happen to her and when so much happened security didn't even turn up and asked us what's. Happening. All the staff are very rude in behaving with public which is not right, could someone please take an action on this?
