Worst Service from Pick N Pay Witpoortljie

Got to the Spice Counter, checked the price and picked up the product, off I went to the Till, after paying I checked the slip and the price is extra, asked the lady to please go back to the shelves to check if I made a mistake, took a photo and went back. The lady agreed something is wrong and suggested we call the supervisor, I said aggg it's not necessary it's ok since I already paid. She said No Sir let's find out what's going on and insisted calling the Supervisor. Now this is where the problem started, the female supervisor comes and looks at my slip and the photo I took and says: The price you talking about is for a different item not this one, I said but it's under the product I took, then she says "hey it's not our fault that the price is wrong, it's the Packers fault don't be mad at us!", I said, I was merely asking why the price is different, instead of explaining to me why you telling me it's packers fault? I noticed we were creating attention and decided to drop the conversation and walk away. I buy there daily and I'm very ****ed at her attitude!
