Misleading advertising

I am in desperate need of turtlenecks to wear under my uniform at work. I was happy to find a heavy knit ribbed turtleneck jerseys on the Queenspark online store. However, the preview says that they are R299, but when you click on it, it is R450 (each). Very misleading and wrong. Then, advertised on the site is that if you buy 3 knitwear items, the third is free. That turned out not to be the case either. So I ended up paying R1425 in total simply because I am desperate and I am cold in my uniform. I am a nurse, an essential worker in the frontline of this pandemic, and all I needed was some warmth at a reasonable price (nurses are notorious for earning poorly. I paid an extra R151 per Jersey, totalling R453 because of false advertising. The preview advertises it as R299, and yet you sell it for R450. I am very disappointed. I truly feel that Queenspark should own their mistake and refund me the extra R453 I spent due to their mistake and simply because I am desperate for thst or a similar item. If I wasn't working around the clock attempting to save lives, I would go to the shops myself and look around for a reasonably priced turtleneck. I have screenshots of everything to back up what I am saying.
