Beware of buying online from Race Shop SA

I went to Raceshopsa website and ordered a pair of 100% Armega Falcon 5 goggles which are clearly listed as available and on sale for R 1 799.00. I order the googles, thankfully I had not paid for them. Several hours later, I get an email from "Courtney" saying that they don't stock the goggles that were clearly advertised. Would it be "okay" if I took the one's that she has sent through in the attachment which is markedly different to the one that I ordered. I open the picture and there is a sticker on the goggles that Race Shop wants to palm off on me listing them at R 1 600. Firstly, if you don't have what I ordered in stock, it should reflect on your website, secondly, don't then try and palm off on me something cheaper that I didn't order from you in the first place at the same price when the photo that you sent as an attachment clearly shows that it's cheaper. Shocking service, I will not be back.
