Shyam Electronics - Abusing and yelling me and my father in market without no reason

I went to this shop called Shyam Electronic located in Farrukhnagar Market, Gurgaon, Haryana PIN-******, for the price of the tubelight. I was supposed to purchase the tubelight while my return from the market as I need to purchase some more things. After he told me the price I was leaving so from back side he yelled " oye gaandu , chutiye jb saaman kharidna ho tbhi aya kar , time waste krne nhi bosdike " . I said you have opened a shop so its your duty to give details regarding the product. He became angry and came running behind me and abused me and my father without reason and was on the hype to fight with us.
