State Bank Of India [SBI] — im complaining about sbi barakar branch manager

Address:

SBI Barakar West Bengal West Bardhaman District., 713324

My mother and sister receives the pension of my father.
My mother is admitted in a hospital so i went to submit her life certificate other years another sbi branch accepted the form of my sister without asking for a proof of her life.
This manager' sanjeev singh' repeatedly asked what proof your mom is alive he was calling 10 employees to attack me.
I felt extremely harassed.
We expect empathy from the public officers. They can't be attacking our emotions. Im just a 18 year old. Doctors sign was important in the life certificate i had no idea about.. He instead of explaining me properly kept on being rude which lead to me walking out of the bank on his face.
Sbi other branch did accept a scanned copy of my sister's life certificate since she was not here but this branch harassed me in this case as well. Scanned copies are allowed if the sign is verified he simply saw me a child and harassed me.
Please take some action towards him morover he told.. Sometimes we favour you but then you make a practice.. Why will a manager do favours? Rules are rules. Who asked him to be favourable.. If he does something for 2-3 years back to back customer will find it right. If one branch is accepting the life certificate of my sister by talking to her over phone or video calling her how can the other branch of the same bank ask my sick mom to be present in front of him who is admitted 200kms away.
Please do take some actions.
These are simple examples of harassment and hypocrisy.
