Yes, you can dispute a transaction with the bank if your same card was charged more than once. Be sure to provide the date that you cancelled/returned the product or service, be prepared to summarize your reason for your dispute in your own words and provide any important documentation to help us support your claim when you file the dispute.
The easiest way to file a dispute with Republic Bank is by visiting More Services in your Online & Mobile Banking account – select “Self-Service Center", then open the Dispute Transactions form or by tapping Services in the Republic Bank Mobile app menu.
