Delhi Metro Rail Corporation [Dmrc] — Misbehave by cisf employee

I was entered from platform number 2 side at Shaheed sthal new bus adaa metro station on date 15/03/23 time around 15hrs. When I was entering from security check suddenly machine light gone and they told me to go to the other side, I asked them to check manually my little backpack on that they refused to check manually and the person standing to check me used inappropriate language like tu tadak that was not expected from a person like cisf who are dealing with many passengers in daily routine
