We experienced something similar.
Recently, paypal misunderstood a transaction valued around $250 as unauthorised transaction and reversed the transaction without notice. The items were on its way from interstate and were delivered the day after paypal reversed the transaction.
We have evidence that it is not a fraud transaction because of the following reasons:
1) Customer emailed several days after his purchase to confirm he made a purchase and requested a follow up on delivery
2) Customer contacted paypal the next day and paypal then reversed the transaction
3) No further email from the customer except a week later when he emailed to tell us items were delivered and that he contacted paypal before because there was no response from us
We've been in contact with paypal for over a month and there's still no solution. We've been told because it is a fraudulent transaction, we are not eligible for seller protection, hence the money was taken out from our account. The person we chat with kept saying it is a fraudulent transaction although we provided screenshot of the customer's email showing it was a genuine purchase. Only today, we've been given an email address to escalate the issue. There's no guarantee this will be resolved but we're still trying.
