Be extremely careful and document everything - this happened to me with Amazon when I ordered a high end graphics card, and got an empty box. They said to send it back, but when they got it, forgot all about the part where I said the item was missing and claimed I didn’t complete the return. Then they claimed to my credit card company I never requested a return. Then they told the state AG that they had accepted my return when I filed a complaint (perjury!) In the end, I lost 2500$ USD. YMMV
