I like the standard wheel as well, but I would demand to replace it immediately, even if that means taking off some of the cars in the stock.
But you really need to check what is it that you ordered, maybe at that moment they had some crazy setup, M with SE wheel, who knows. VIN is not helpful here since it's just telling you what is actually in your car and not what you ordered.
They cannot put the wrong wheel just because they are out of stock of the right one. In this case car delivery would have to be delayed.
If they could do this, they could out whatever they want on the car, why stopping at the st wheel, let's put 16" rims as well
