Display incorrect pricing

I visited Cross Trainer at V&A so th was this lovely tekki caught our attention, so this guy was so helpful checking sizes for us 🤣🤣it's not funny but I'm laughing th display price was R1499 when we got to the point of sale th cashier told me it's R1700 i told her i want with the price that it's on display she move away from the till with no care made it look like was my fault with a stinky attitude, i ask for the management i was told it's off. I will never set my foot again, i even took a picture
