State Bank Of India [SBI] — ATM security guard

Address: New Delhi, Delhi, 110009

The sbi ATM in outram line, next to venus, has a security guard probably over 40, more than a guard he is a threat. I entered to take out some money, spoke politely to him. He started shouting suddenly telling something which I couldn't comprehend and he kept repeating the same thing over and over again, getting very aggressive. Still, politely I asked him to come and show me what is wrong, he got angry with me and started raising his voice, saying "don't you even know that much. I am telling you and you are not listening to me". I said I don't even know what you are talking about, then he looked back aggressively making a disgusted face at me, thats when I walked off. You can even view the CCTV camera to get a better understanding of the situation that I had faced.it happened on the 23rd of feb, 2017 around 8:40 - 9:00. I really hope that you will take this matter seriously and do something about it.
I got scared of that man because It was just me and my cousin and I didn't know what was wrong with him.
Please see to it that something is done about this man, because if action isn't taken I'll take it in my hand and report to the police station which is just about 50 meters from the sbi ATM
