Can I stop or cancel a transaction while it's pending?
A pending transaction can only be cancelled if the merchant provides us with a pre-authorisation release confirming they have no intention to debit the restricted funds. As the merchant has authorisation over the funds, we cannot release the funds without their authority.
If you believe a pending transaction is unauthorised, once the funds have debited from your account, we can help you dispute the transaction. Please send us a secure message via Internet Banking or the Mobile App with details of the transaction. Alternatively, you can call us on 13 25 85 or visit your nearest branch.
