For our mutual security, each credit/debit card payment made at Foot Locker Australia is processed through an automatic payment verification system where the order details you entered are compared to those registered to the payment card. In case the system cannot verify these details, it will automatically cancel the order. If your order was cancelled for this reason, it probably means that there were inconsistencies between your billing and shipping details (think typos, misspellings, or maybe inserting the details of a different card). Carefully check these details before submitting a new an order again, or try using a different card or payment method.
Since the verification process is automated, our Customer Care team cannot tell you the exact reason for a cancellation of this type. Sorry!
