Unfair display of price

I always like shopping at Clicks but today I was disappointed in the unfair adverti*****t of prices at the Baywest branch. The price on the shelf was R105 but it scanned R170 for the gold toiletry set in the bag. There was no other price displayed just 2 stickers of R105. The manager Sharon the manager said sorry it's new stock. So she said the price sticker was not available to be placed on the shelf and the customers kept on moving the stock around. She admits it was the correct shelf just that the incorrect sticker was placed in front of the stock, which she moves away from the gift packs to the left items. She continued to pack the 2 gift packs back on the shelf and wouldn't budge although I told her that if the incorrect price is displayed and the price of the item is not available surely I must get the item at the displayed price ? Unfair adverti*****t.
