The person on the other end told me that she could only handle lost and stolen cards, not fraud, and given that I'd already frozen the card, I should just drop by the branch on Monday to get a new card.
We flew home, and later the next day, I logged into my account and made a list of all the fraudulent transactions and printed them out, and on Monday morning, I drove to the bank to deal with all the paperwork. The folks at the CU were even more pissed than I was.
