Incorrect pricing displayed.

I went to buy a under wig glue @ Clicks in Escourt, on the shelf I found the Eco Styler underwig glue and there was a price of R109 ,but when they scanned it @the checkout till it was R250 and I told them its marked R109 , I even went and got the barcode on the shelf where I found it I was told that the correct price is the one at the till not the shelves, I asked for the store manager and I was told that she/he is not around . The consultant that is responsible for the product said maybe there was another product that was packed at that shelf and when it got finished they just packed something else and didn't change the barcodes, she didn't even bother double checking what is the correct price for the item or even apologize for the inconvenience she just carried on as if I was being unreasonable for bringing up the incorrect pricing.
