As shoe said, we would never do this. While I do not know exact details, I know that no one in Customer service department has any access to any cc, banking data. That info is proprietary and we have to escalate those (that's why they take longer to resolve).
I know it's easy to blame the first thing you can, especially when it comes to something personal as this.
to OP: If you gave them your credit card info, close cc and have your bank reissue u the cards.
