Misleading advertising

Halfway Toyota George advertised a Toyota Rav 2.0 Gx 2016 on Cars.co.za for sale. I enquired about it by speaking direct to a salesperson( Mr Shorp). He checked for the vehicle as we spoke and said yes they still have it. As soon as I mentioned the price it's advertised for, he started stuttering saying " nee hier's ń helse fout ". I said that thats what its advertised for and I'm looking at the ad on my computer screen as I'm talking to him on the phone. He said his gonna put me through to someone else whom I can speak to about the vehicle. For some time I was put on hold. Eventually when someone answered it was a Mr JP something. I told him that I'm enquiring about the advert and he told me that the vehicle has been sold already, which was really funny seeing that a few minutes ago the salesperson I first spoke to told me it's still available. He only realised the price after I told him for what it was advertised for. Once again a gaint can go ahead and step on an ant and get away with it. The giant( Halfway Toyota George)..and the ant ( me the hardworking, honest income generator consumer. If there is anyone out there that can relay to this, is there nothing that can be done to this.
