if you login to someones account (even with the correct logins) if it isnt a ps3/4/psp/vita that has been used before it will ask for full card number and ccv before you can continue, if you dont provide them it removes the card info from your account. and even if it didnt, the first thing they would do is change your password and buy shit, if you can login still and nothings been bought, and you have no purchase confirmation emails, seems pretty obvious it isnt the issue.
So no, it wasn't psn related.
if someone has your full card number and ccv, you're screwed anyway.
you cannot extract card info from a psn account by knowing the logins.
