MasterCard Chargeback Reason Code 4999: Point-of-Interaction Error

chargeback reason code 4999Merchants who receive a chargeback for a transaction placed with a Mastercard card may encounter reason code 4999, which indicates an improperly authorized transaction that the cardholder does not believe they should be responsible for paying. The actual underlying cause of this chargeback is usually either friendly fraud or merchant error. Merchants who believe they have received an invalid chargeback under reason code 4999 may be able to represent the transaction and reverse the chargeback with the right compelling evidence.

What is Mastercard Chargeback Reason Code 4999?

Mastercard chargeback reason code 4999 falls under the “Point-of-Interaction Error” category. The shorthand description is “Domestic Chargeback Dispute (Europe Region Only).” This reason code is used when the cardholder claims that a transaction charged to their account was actually supposed to be a credit. This reason code is only used for disputes involving parties located in Mastercard’s European markets.

A generous and flexible refund policy is one of the most important ingredients in good customer service. Offering a refund is often the easiest way to resolve a customer’s problems, and can help you avoid disputes and chargebacks. True, you have to give up some revenue, but at least you don’t get hit with chargeback fees or a dangerous increase to your chargeback ratio.

However, few things will upset a cardholder more than seeing a transaction that was supposed to be a refund taking even more money out of their account. When this happens, the cardholder has chargeback rights, and will surely exercise them.

What Scenarios Might Lead to This Chargeback?

Usually, this chargeback happens because of merchant error. The merchant is trying to process a credit transaction to issue a refund, but because they are distracted or unfamiliar with their payment processing system, they run the transaction as a regular charge instead, debiting money from the customer’s account. Now the customer needs twice as much money returned to them—and at this point they will often write the merchant off and choose to deal with their issuing bank instead.

It’s possible to see this reason code used in friendly fraud, but it’s a fairly bold gambit.

As long as you have complete transaction records that specify the reason for the transaction and purchase details, you should be able to fight it.
