I bought the jacket from ticktock shop. They sent the wrong size, I can’t fit it

This fur jacket is cute but they sent the incorrect size. I ordered a M, they sent me a XL. It’s supposed to be slightly cropped. A person who wears a small, medium & large can fit this comfortable. The first pic I have a thick sweater that you can’t see underneath so you will have room. Still have tag & care instructions attached.
