State Bank Of India [SBI] Panagal Park — Rude staff. Very hurtful.

Address:

400017

Dear sir,
I visited the sbi panagal park chennai branch along with my mother to include my name as nominee for the locker.Since my mother would be travelling to usa in a week."the lady responsible was really rude stating how can you come just like that .Things will not happen in two days" and started scolding me and amma.My mother is 66 years old.Today april 6 the is a bank working day.So i fail to understand what is my mistake.Also we had travelled from hyd just for this, i work in hyderabad.
She refused to even mention the procedure.She was really arrogant and she has really hurt us.She could've said the same thing politely...She sits in the far end of the bank locker section left most seat.I failed to get her name.
Can you please suggest them that there are old people .And as a customer it is our right to avail the services provided.Why such arrogance and irritation ?
Regards
Priya
