The charge on your credit card may just be a reservation rather than an actual charge. During the purchase process, we send an authorization request to your credit card to verify that sufficient funds are available. This is often shown as a booking or reservation on your credit card statement. It is not an actual charge. If the purchase subsequently fails, we cancel your transaction and remove this reservation.
Some credit card issuers may not immediately show the transaction as removed, even if it has been. We assure you that funds were not withdrawn from your credit card and we have reversed the authorization request. If you have any doubts or require additional confirmation, please check with your credit card issuer or financial institution to verify this. As a guideline it may take up to two weeks to clear these transactions from your statement, but typically the time period is much shorter.
