State Bank Of India [SBI] — Rude behaviour of bank staff

Address:

STATE BANK OF INDIA, BIJOYNAGAR, KAMRUP, ASSAM, PIN 781122

Sir
myself deepmani das. Recenly my father expired. Yesterday i went to sbi, bijoynagar br for enquiry how to convert my father pension to my mothers account. That branch manager simply gave me a form and told what to do. Also asked me to open an account for my mother.
For this today i came with my mother to open an account. We have reached at 11:55 am. But i m shocked. The lady employee named Mrs Sikha told me if we want to open account we have to come at 10:00 am. Otherwise no.
I told her that yesterday i came and discussed with bm. But she rudely shouted i am the authority to open acc. So you have to ask me. For this i request her as my mother is a senoir citizen and physically weak plz consider. We are ready to wait. But that lady named mrs sikha doesn't have any manner how to talk with customer and with a senoir citizen. Everytime she speak loudly. Is this the way that state bank employee treat with customers. Very rude behavoiur, nonsence person and hopless staff.
I am very upset with this and request concern authority to look after this.
Is there any circullar in sbi that a bank cant open an account after 12:00 pm ???
