Ok auction ends, payment's received by paypal. Go to auction get address, box item. All well and good.
Then BANG, I check Paypal [ok I normally take address from them first then compare to eBid].
The account has a totally different name and address. Hmm strange. Contact buyer - no reply. Contact buyer 3 days later no reply after 3 more days. Contact Paypal who couldn't give a sweet Fanny Adams, but say don't send, and after pushing agree to forward the account details to their fraud investigation dept. Without me letting them know which payments out of 3 recent was the problem [ so I force fee agent this information - highly doubt he could be arsed if I'm honest].
Now waiting to see if I am covered by FVF refund policy as technically I was paid even if it was a case of fraud. It's bad enough NPB but glad I checked and didn't get stung by paypal reversal and loss of item.
So in ending please always check Paypal address first , if it doesn't match up & don't send until you have spoken to buyer
