GOOD! Thanks for the info! I'm old and not very well informed on these matters.
You're just danged determined to have the last word I'd say, just to prove you're right. Whatever, I DGAF.
But to answer your question,
IF they had my card (low on the order of possibilities) they would have the CC number and the CVV2 number that's it. Billing address and ZIP would be a challenge even with Google showing only 25 similar names. If someone HAD your card and you didn't know about it (or lost it) in order cancel the card you would be quite the inattentive moron. Besides, the liability would not be on me (unless I completely failed to report) regardless. So, as they say, no big deal...right?
