Unfortunately, things don't always go like clockwork when using credit cards. The credit card company might make a mistake on your bill, a merchant may overcharge you, double charge you, or charge you for something you didn't buy. Or, you may have a dispute with a merchant over the quality or some other aspect of the goods you bought, and don't feel you should have to pay. And finally, what many of us dread more than all -- someone could get ahold of your credit card or credit card number and make unauthorized charges.

Check out the articles below to find out what to do in the case of billing errors, unauthorized charges, or merchant disputes.
