State Bank Of India [SBI] — Disrespect to women customer

Address: 521230

On 16/5/2017 My mother went to sbi pulluru branch located at mylavaram to know about how to get new ATM card of me. I am in other Australia pursuing PhD.
The case manager (name I don't know) was very rude to my mother and insulted her very badly in front of so many customers.
I request you to please take immediate action on him. I will complain to this in ombudsman also if I am not satisfied with your action. I want immediate action. He don't know how to serve customers especially with women. Yesterday he is in charge of that branch.
