I paid for a laptop screen from China which never arrived. I claimed for non delivery and PP judged in the sellers favour because they produced a tracking number. When I tried it - it said the item was delivered to a different postcode. Don't PayPal check this basic info? I guess they sent one to a nearby address and used the same tracking number - I checked with the local sorting office - no luck. PayPal is helping scammers by not checking postcodes.
