If I understand, you bought the Domain Buying Service? If so, that is refundable, but ONLY IF you have not submitted a bid on the domain the service was purchased for. I would say contact 24/7 Support as soon as you can to be sure you get what you want in a timely manner and the back-order applies if it is needed.
Best of luck,
