Early this year Paypal software sent $500 to the wrong recipient. I complained online and was told to contact my card issuer and after a while Paypal told me online that the recipient would not return the money and the case was closed. I also complained to my card issuer who are acting but Paypal are refusing to cooperate have said that I should have contacted them first. Paypal are just downright dishonest as their mistake is obvious from their own reports on the transaction.
