There are a number of reasons you may need to dispute a debit card transaction that you previously authorized. For example: if a merchant overcharged you, you continue to get billed for a service you cancelled, or you didn't receive a shipment you paid for, you have the right to dispute those transactions.
In all cases, Visa requires that you first attempt to resolve the matter directly with the merchant. If your efforts are unsuccessful, we'll do our best to help obtain a refund for the disputed transaction.
Please complete the Visa Debit Cardholder Dispute form and provided it to the credit union to begin the dispute process.
