Mother Dairy — REFUSE TO GIVE MILK

I AM LIVING IN AZADPUR mcd COLONY NEAR METRO STATION, THERE IS MILK DAIRY THERE. THE PERSON WHO IS OPERATING THERE IS NOT GOOD IN BEHAVIORS ALWAYS FIGHT WITH THE PEOPLE. MY COMPLAIN IS THAT RECENTLY MY MOTHER GO TO THERE TO BUY MILK, HE SAID THAT THERE IS NO MILK BUT AFTER 5 MINTS, MOTHER SAW THAT ANOTHER WAS BUYING MILK PACKETS, MEANS HE REFUSED TO GIVE MILK PACKET TO THE MOTHER. WHAT IS THIS?
