Mastercard Chargeback Codes

There is probably nothing more frustrating in business than to learn that a customer has initiated a chargeback without calling you to discuss why or what you might be willing to do to remedy a problem. You might become even more frustrated as credit card companies use codes to determine the reason for the chargeback.
