Saraswat Bank — denied a muslim girl to enter the atm

Address: New Delhi, Delhi, 110018

I want to complaint about the guard of your atm at lajpat nagar4, new delhi branch as he didnot let my friend to enter the atm, and demanded that she needs to remove her hijab. He clearly said that ‘this is not allowed’ while smirking and smiling. I just need to know if there is any rule book where it is mentioned or he was just hired to insult the customers. I demand his immidiate removal and apology to my friend. This is absurd how your guard behaved and for future they need to be taught how to behave and proper training. Please resolve this issue as soon as possible.
