State Bank Of India [SBI] — misbehavior of a bank employee

Address:

New Delhi, Delhi, 110006

I'm a student and I'm going to this bank from last 5-6 years.A month ago, i went to the bank to get a new passbook.At the first place the service manager argued for the photograph. Now today when i went again he rudely said that "jaa vahan se karake laa" and threw my new as well as my old passbook on the floor. I told him that last time he said he'll do it and today he said "maine jhaadu lagane ke liye bola hoga to mai kya vo karunga". I was talking politely but then he started shouting. Government employee's duty is to serve the public and doing his/her job at his best but how will the public cooperate if this will be the employee's behavior?
