Another menineshop victim. PayPal has been ruling in those guys favor, I have no idea why. They take their domain down, the emails come back as undeliverable - both tactics commonly employed by shady hit and run companies. They apparently come up with a tracking number from some Chinese shipper that doesn't even operate in most of the US and, and PayPal just believes them.
Maybe the fraudulent company gives kickbacks, who knows. All I know is that there is plenty of evidence for PayPal to rule in the customer's favor and they ignore it.
But to answer your original question, just screenshot the "delivery failed" email with your attempts and upload them in the resolution center.
