<human>: What should I do if my credit card is lost or stolen?
<bot>: If your credit card is lost or stolen, you should contact your bank as soon as possible and report the loss. Make sure to keep a copy of any documentation related to the card, such as receipts, statements, etc., in case it needs to be replaced. Additionally, you can place a fraud alert with your credit reporting agency so that future fraudulent activity can be flagged.
