If your naive enough to think criminals all over the world aren’t looking
Your sadly mistaken
I've had my actual identity stolen by some guy in Texas working under my SSN, so spare me the lecture.... and you still haven't even proffered an hypothesis on how they got your card# if in fact you've never typed it into a website or used it at a gas pump for that matter. What are you suggesting, somebody used telepathic powers to peer into your billfold to get your card #?
It isn't in the issuers interest to have a card hacked. They will have to refund you that money. They will also be interested in knowing why they are refunding money to you for a third party theft on a never used card.
If ya ask me, I'd be asking a family member if they used the card..if in fact this is a never been used before card to the OP's knowledge.
