Liberty3D.com sold me pirated materials!

I went to www.liberty3d.com back in December when I saw them selling some really nice explosion plates for the great price of $9.95. I bought several live plate elements for use in my commercial product. I was later notified by the real producer of the materials that the items I purchased were pirated, not to be resold, and I was not to use them in my production. Soon after the pirated materials were removed from Liberty 3D 's web site. I contacted liberty3d.com but I was refused a refund and only offered store credit. I also posted information to their forums, what a joke, my information was removed and replaced by the site admin as a bad post.

Why would I want to buy anything else form this merchant! Why would anyone trust them at all?
