"Hi! Apologies for the late response—you definitely didn't get scammed. The purple color is just Blender's default way of saying it doesn't know where the texture images are saved on your specific computer.
You can fix this automatically in just a few clicks:
Go to File > External Data > Find Missing Files. Then, find and open the Textures folder included in your download and click 'Find Missing Files' again.
Blender will auto-link everything and the map will look normal. Let me know if you need any more help getting it set up!"
