Something is beyond wrong if a verbal "not as described" lets them keep the object. That's such an obvious scam/abuse there should be a legal issue with it, if paypal is not pursuing actual proof. They are acting in bad faith because their contract/terms of service is not even plausibly verifiable. The CC company requires an affadivit to issue a refund; if Visa gets wind of this guy with 5 refunds to the same card/provider/etc (thats 5 perjured affadavits) it should be a verifiable problem with paperwork. Paypal should be in the business of verifying this; not denying it. Its so basic as to be beyond belief. Apologies for preaching to the choir.
