False Price Advertising on website

I went on their website trying to search a car to buy, as I now have a huge need of a car, to go to work, and one caught my eye, a VW Polo going for R54000, just the perfect price and car that suits me, I phoned their call centre so that I would be the first to get hold of the car, and so that I could go and buy it. I spoke to their call centre agent who kept on putting me on hold multiple times and then they then told me that the price of the car had changed to R132000, I then requested for a number to call someone (CJ) who works at the silverlakes branch to confirm, and they treated me like I was a fool and I didn't know what I was talking about. He told me to check again on the website, and said maybe I was on the "old" website, like is there a new and old website?? I took screenshots of both the "old"and "new" prices to show, and they were not interested. That is just one bad experience to go through and have ones hopes up for nothing.
