You'd lose that bet. They refund the money to the original payer. For better or worse. My company loses a few hundred euros each month to this. They keep asking for proof of delivery. Yet we sell internet access. No proof in that unless I'm willing to break the law (and my client's trust) and tcpdump my clients. No way I'm doing that so I swallow the losses. No client ever filled a complain in the first place and no client ever complained about returned funds for consumed services either. :P

To get around this situation, mark your paypal invoices as 'Services' and they can not refund them at all (unless however the card was stolen, etc). But 'Services' don't require shipping proof.

Thanks for the advice. Will look into it.

I'm sure they do that on a bit by bit basis, when they're isolating one transaction at a time, but are you sure that when they 'freeze' an entire account, they reverse all of the transactions?
