Union Bank Of India — unprofessional conduct of branch manager

I've availed an education loan for uk higher education in union bank of india. The loan sanctioned letter given is not approved by experts because it highlights certain points that it implies the loan is not yet sanctioned. When requested for a feasible format me and my father were shouted at. This is not a response we'd expect from a professional with 35 years of experience. Unnecessary attitude and arrogant behavior is not something an official can exhibit. All our kind requests were turned down along with a series of shouting and slamming of the telephone. He is unapproachable and highly insulting. We are people with needs but still expect basic courtesy and respect from the officials too. This is highly insulting and unsatisfactory. It would really be helpful if these points are considered and corrected sooner.
