File a claim. Get $ back. Btw you might want to look at the news behind the USPS and the back log of packages. A location changed a machine, now they are almost a 6 months behind. It may still show up but you are backed by eBay buyer protection.
They might also be good about it and send you a replacement. Clearly it's lost. They will get $ back from shipping from USPS. Btw. Never send anything any way other than ups.
