Did you do DNA or SNAD in the PayPal claim? If you did SNAD and they didn't respond, they can't do anything. Either way it would be tough for them to do anything even with DNA. They agreed to PayPal's terms and conditions by accepting them as a form of payment. PayPal ruled in your favor so unless they caught you using/signing in to the items you didn't receive, I don't think they have a leg to stand on
