Humiliation

I am writing to express my deepest most painful encounter. I was at Spar in uMhlanga today. I went in the shop. Bought a few things and took a packet of sweets before I paid at the till. The sweets scanned lower than it shows on the shelf which I thought was great for me.So I went back and took two more packets of the sweets to my surprise when I got back to the til some lady who I think is the manager of Indian ethnicity, together with other 2 accomplices came to my till and she shouted at me saying that I will not leave the shop with those sweets as I paid a price which doesn't belong to them and the price I saw is not the price that I am paying right now. So there is no way she will let me out of the shop with those sweets. I am telling you the humiliation at the shop. People stood still, I felt so degraded. So humiliated as I am not a *****, I took packets of sweet.They scanned a certain amount.I paid with my money but it she made it seem like I was *****ing from the shop! She made me feel like I am nothing, I could not even say anything I stood there, she took the sweets, took back the slip, I had to stand while my time at work was up. I refuse to let this slide, I am not sure if that's the treatment is based on classism or ****** behaviour, but it stems from somewhere, I am a law abiding citizen, a Spar customer, who was DEHUMANISED. I AM BEYOND heartbroken, livid, and anything in-between.
