If you discover fraudulent transactions on your credit card account, and you still have possession of your credit card, then you may likely be the victim of an Identity Theft. To learn more about Identity Theft, please visit the Identity Theft FAQs.
Please keep copies of all transactions showing the fraudulent transactions. If someone signed a credit card receipt in your name, then they may also be committing a separate offense called Credit Card Forgery.
