Once a payment is submitted through Aeropay, it may not be possible to cancel it directly.
If you need to stop or reverse a payment, contact the business where you made the purchase as soon as possible. Depending on the payment status, the merchant may be able to void the payment before it is fully processed or issue a refund after it has processed.
If a void or refund is issued, you can check your Aeropay Activity feed for updates. Any returned funds will appear in your bank account once your bank posts them.
