This can occur upon clicking 'check out' prior to the billing screen, or when clicking 'purchase' after completing the billing screen. You may or may not have been charged. It is suggested that you check 'My Profile' after waiting a few minutes. If you were applying for the test, see if there is an E-ticket link for that test date. If no E-ticket is showing, then the application didn't go through. However, if there is an order ID, credit card type, and amount, then you have been charged even though no reservation was made. If you were charged and no reservation made, please call technical support at 800-249-0659 for assistance.
