Why does the Pending Transaction appear twice for the same transaction?

If a Pending Transaction appears on your Card Account twice, it does not necessarily mean your Account will be billed twice. Certain merchants, such as internet companies, may authorise a charge when you place an order. The merchant may then authorise your Card again when the amount is due. In these instances the charge may appear twice in Pending Transactions but will be billed to your Account only once. If you discover duplicate transactions on your billing statement, you should dispute one of the charges via your Online Account or by calling us on the number on the back of your Card.
