Poor customer experience

I had the security guard (Edwin) swear at me for not doing his job. I got to the door after I made a purchase and one of the items alarm. No one was at the exit so I went back inside the store to have them check the items properly. One of the cosmetic consultants quickly ran to assist as I waited on the exit come a security guard (Edwin) then he said "hey hand me the slip" and when I confronted him about his approach he became defensive and turned the whole conversation into an argument and giving me attitude, I felt so disrespected and inferiorated. When I went inside the store to report him he went on with the attitude even when reprimanded by one of the staff members he even walked away, appalling!
