DMART - Unacceptable Rude behavior by Manager Anith and employee

I have visited for Banglalore Kaikondrahalli DMART store with Family for Diwali shopping , We are carrying infant of ** months and another small child of * Years done with the shopping and brought Pizza at Dmart food counter, and no place to sit and as they not able to stand for long time and I and my wife with kids sat on the steps near by, one person has come very aggressively shouting to us in abusive manner , whenever i asked him for his manager, He is saying go and complaint to whomever you want. I took this issue to the store manager and explained him the issue, am surprised they didnt even ask for sorry and very supportive to the person who is shouting to us.
