Security humiliated me

Today I got humiliated by the security guard at the entrance when I returned an empty box of a gentle magic product because I forgot to tell the cashier after purchase to put the product inside, the lady said to me how come I didn't notice the box was empty, and why the receipt was a bit wrinkled and what if ngiyamshsyaya, she went on an on looking at me on a funny way. I told her to stop making noise at me, it's either she assist me or not. I felt so embarrassed and humiliated, I was never never made felt like that in my entire life, I don't wish to put my feet ever again at this store
