When you are issued a refund to a Visa or Mastercard, a refund authorization check will be sent to your account. This can, on rare occasions, cause a pending "charge" to appear on your bank statement. Simply put, this is due to your bank having not yet updated their system to display the refund correctly. We are not charging you again for your order. We suggest that you contact your card issuer for any further information.
You can also find the acquirer reference number (ARN) of the transaction on the order page or refund details page and provide it to your card issuer so that they can trace your refund more easily.
