Incompetence: Insured the wrong car model

I bought a BMW X5 G05. My current car is also insured with King Price. They could not match Santam with the BMW,so I took out the cover with Santam. Someone from King Price phoned me asking why I did not went ahead with their quote,I told them because they were way more than Santam. The guy asked me how much and how much the excess and he told me they can beat the quote. I cancelled with Santam and took the cover with King Price. When I went unto the app to do the inspection,I noticed that they have the wrong model under cover. So according to them I have a 2*** model. I have the new model 2019 to date. Consequently I am not covered not because they listed the wrong car
