The following article talks about the cancellation process for reservations where a pre-authorization or prepayment was made.
Depending on the cancellation policy of the venue which the reservation was made, a cancellation fee may be applicable if you are cancelling within the venue's stipulated cancellation window.
If you are cancelling your reservation outside of the venue's stipulated cancellation window, the credit hold placed on your card through the pre-authorization will be released accordingly and reflected on your statement in several days.
Prepayments are not subjected to refunds generally, unless stipulated by the venue.
If a refund for a prepaid reservation should be provided due to extenuating circumstances, please contact the venue directly to provide more information.
If a refund is expected as you are cancelling outside of the cancellation window (as stipulated the venue), please cancel your reservation and await the venue's refund action accordingly.
