Sold a car on false pretences

Hi, I want people out there that is reading this to know that Toyota(Especially Toyota Uitenhage) and Wesbank should not be trusted, I bought a Ford Figo from them in 2016, I was informed that I'm buying a Ford Figo 2015 model, the contract I signed with them said I bought a Ford Figo 2015 model but the car that I'm driving for almost 3 years is a Ford Figo 2014 model, I'm paying for a 2015 that is abviously more expensive then a Ford Figo 2014 model, Toyota Uitenhage is denying the fact that the vehicle is a Ford Figo 2014 model even though the manufactures of the car(Ford South Africa) provided proof on black and white that the car I'm having is a Ford Figo 2014 model, a Ford Figo 2014 is different from a Ford Figo 2015 model, the responsibility of a dealership is to make sure that everything regarding the car and the documentation is correct, the dealership has been doing this business for many years so there is no way that they could've missed this, they can't sell a car to a consumer if they don't have the full information of that car, they knew that the car they have is a Ford Figo 2014 but they still sold it as a Ford Figo 2015, this matter will be reported to the Motor Industry Ombudsman and after that it will go to court if it's not resolved, because Toyota Uitenhage has sold me a car on false pretences. That is against the law in South Africa, how can a dealership(Toyota Uitenhage) and a bank(Wesbank) rob me in that way, how can registered companies like Toyota Uitenhage and Wesbank conduct unfair business Practise in this way.
