If your order fails due to issues such as the billing address postcode not matching the one registered to your payment card, the transaction will not go through, and no money will be taken from your account.
However, in some cases, your bank may temporarily reserve the funds. This is known as a pending transaction—the money hasn’t been taken, but it’s been set aside in case the payment is approved.
These pending funds usually return to your available balance within 1–2 working days, depending on your bank’s processing times.
