You haven’t won €500 from PayPal
There is a draw taking place but PayPal say “Unfortunately, this email has been sent due to a technical error. For this we apologize. The draw has not yet taken place. We just identified the transactions of our customers who are eligible. Then there will be a raffle amongst the eligible customers and the winners will be notified in a separate email”.
If we find out how PayPal intend to clear this mess up we’ll let you know. Currently it appears that there should only have been 10 winners per day. The winners should have been drawn from PayPal users that had made a purchase with their PayPal account that week.
