PNB — rude treatment by bank staff

I am very upset with the rude behaviour at pnb salt lake kolkata sector 5 branch. On[protected] i went to kolkata in order to reissue a new atm as my previous atm card stopped working. I was really upset by the way they talked to me calling me stupid because of a small mistake from my side that happened because of their misguidence. When i objected about their rude comments they said this is lunch time we wont do anything now come after 2:30. I requested them to take extra 15 min and do my work beacuse i had a flight to catch. After my repeated request to process my application because it was an emergency for me as i was having a flight to catch i asked then to process my application they told me are you some vip or something that you are coming at this time and telling that you have to take a flight. I was really very upset hearing this because they are commenting on me saying thst if it was so urgent why you came at this time, couldnt you come early. One staff said this in a harsh commenting tone. I told them i don't live in kolkata i have come from out of station taking early morning train to pnb bank in kolkata because the bank i visited in my home town informed me that this work of changing the atm card can be done from the pnb branch where i opened the bank account. I am not mad to come all the way to kolkata to do this. And the staff in the salt late branch were very harsh and rude to me. After telling them that being government employees you all are treating the customers as #, they process my application and issued new atm card to me. But now i am no longer interested to use the banking services of pnb beacuse of the rude treatment i got from this bank.
I request to take strict action against this branch of pnb.
