There are times when charges may show up on your statement and you are not sure why. Sometimes these charges are due to fraud, but sometimes they are not. To assist you with making the decision about whether you should dispute a charge or make a fraud claim, review the following information.

The primary difference between a fraudulent transaction and a disputable transaction is whether or not you, the account holder, has used the merchant in the first place.

  • Disputes can arise between a merchant and account holder for a variety of reasons. These reasons can range from overcharging the account holder, charging for merchandise that wasn’t received, or charging for a monthly subscription that was previously cancelled.
  • If the transaction was never authorized or initiated by the account holder, a fraud claim may be filed.

Answering the following questions will help you to determine whether your claim is a dispute or fraud.

  • Do you personally know who made the transaction to your debit card?
    Is the transaction a result of signing up online for a “free trial,” however you used your debit card to pay for shipping or a similar charge?
  • Did you give or loan your debit card to anyone?

When you have a disagreement with a merchant about a charge they made to your debit card, this is considered a cardholder dispute. For example:

  • You cancelled a transaction, but the merchant still charged you. For instance, you used your debit card to reserve a hotel room, and cancelled with the hotel in accordance with their cancellation guidelines, and you were still charged for the room.
  • You purchased an item using your debit card, and later returned the item to the merchant, but your card was never credited for the return.
  • You were charged an incorrect amount for a transaction, for example $500 rather than $50.
  • You have an issue with the quality of goods or services provided.
  • Contact the merchant first.
  • Try to resolve the dispute directly with the merchant.
  • If after 30 days you are either unable to resolve the dispute with the merchant or they have failed to follow through with a promise to refund your charges, contact the credit union’s fraud department.
  • Provide all documentation supporting the transaction and your attempt to first work out the dispute with the merchant (e.g. receipts, emails, names of representatives you spoke with, letters to/from the merchant, etc.).

The dispute process When you submit a dispute, the credit union is acting on your behalf with the merchant. Mastercard® will make the final decision as to whether or not the credit union is authorized to charge back the merchant for your purchase.

The dispute process can take up to ninety (90) days; Note: If Mastercard consents to your dispute, a charge back is filed with the merchant and you will be reimbursed. If Mastercard determines that we cannot charge back the merchant for your transaction, we will withdraw the full amount of the provisional credit from your account within five (5) days of notifying you of the results.

A fraudulent transaction occurs only when you have no knowledge of who used your card and you can state with certainty that you were not aware of the transaction.

Call the Credit Union (516) 822-1070 and Speak to our Fraud Department.
