When I enter my payment details the screen simply refreshes with a blank payment form or states 'Authorization Error'. Did my payment go through and have I booked my tour?

If you have not been directed to a screen that states "Your booking was a success", you have not completed your transaction and have encountered an authorization error. An authorization error occurs when your bank is blocking the charges from our website. As a result we cannot successfully process your credit card to complete the transaction. In order to remedy this, please contact your card issuing bank and let them know that the charges from grayline.com or Trust My Travel, our payment processor, are legitimate and to clear them. Then revisit our site to try your purchase again.
