Deformation of character

Pnp express in Sebokeng zone 20. The cashier just deformed my character, talking about me with other customers.. The card machine had a problem. Instead of informing me, after 4 times my card kept declining. I even changed cards. The machine had problems. So she just came an just too my card from my hand. Held it in. I asked her why didn't you just tel me that I should hold it in. She just threw my card on the counter an left. When the next customer came and experienced the same thing with the card machine. She now started talking about how I'm a child with no money. Getting paid social grant now I think I'm clever coming there to swipe with 200 balance in my life. By that time I was no longer in pnp I was now buying food at the rasturant... I felt so disrespected an hurt. No one on duty did anything about what she was doing....
