When you request a refund, include the credit-card number that you used to pay for the reservation and the confirmation e-mail you received when you paid. If you have lost that e-mail, send as much information as you can about the name and date of the event, the date that you paid, and how much you paid. Refunds cannot be made for reservations that were paid for, but not cancelled before the reservations deadline. When that happens, you are considered a no-show.
