There could have been multiple attempts to make payment for your order. You may see this as a pending charge or payment authorisation hold. However, as the transaction was not completed, it will not be charged to your card. Your bank often sets aside the funds in anticipation of a successful charge. Since the transaction was declined, no funds will be transferred to us.
If you paid with a credit card, you'll see this appear as a pre-authorisation charge or pending transaction.
If you have paid with a debit card, it looks identical to a regular transaction.
Do not worry as this will clear within 3-8 business days, the time varies as per your bank's policy. The transactions will be voided by your bank and the funds will be released back to you.
