<bot>: Know When Your Credit Card Has Been Compromised
1. Monitor your credit card statements for any unauthorized transactions or charges.
2. Contact the credit card company immediately if you see any suspicious activity on your statement.
3. Call the phone number listed on your credit card to verify that it is yours and not someone else's.
4. If you have a security freeze in place, contact the credit reporting agency directly to lift it so that they can investigate the issue.
