PNP Hyper Bloemfontein incorrect pricing

At Pick n Pay Hypermarket Bloemfontein I bought a leave Blower that was priced in the rack for R599 but was charged R1699. I had to go to customer care after taking a photo of what was displayed in the rack and what I was charged and they refused to give the product to me at the displayed price. They told me that I had to look at the model number on the box as the one had a "K" at the end and the other box next to it not. On the price tag displayed it just mention the Product Description - no model number and no where was a price tag of R1699 even close. The boxes looked the same. One manager agreed that the product needs to be given at price displayed as it was their mistake then waiting almost 2 hours they came and told me that they contacted their GM and he said they cant and if I do not want to buy the product at the right place I must return it. That same manager then told me I should have noticed the model numbers. I did however returned it as I was basically charched 3x more but I am still not happy as I feel they violated the CPA ( Consumer protection Act) I am not just going to leave it either. How many people did not fall into the trap of paying more for something and did not notice or got home and did not return as they perhaps stay in rural areas and just come to Bloem for Christmas shopping this weekend?
