If a customer acknowledges they have their debit card saved on a Playstation console, and has had previous charges, but now states her son (11 yr old) stole her card and did the 2 most recent charges without her consent, are we able to deny her dispute? Given that there is a history of transactions, and also with her admitting the debit card is stored within the console.
Part of your investigation should be to find out how the card number came to be on the Playstation. If she provided the card to her son to make purchases - on the Playstation or otherwise - his use of the card is considered authorized until she notifies your bank that he is no longer authorized to use her card. I would hope you then have procedures in place that, upon such notification, require her card be canceled and a new card number assigned.
