Unfortunately just as you will not receive your money back if you do not attend a concert or go to the movie you already purchased tickets for, we do not offer refunds for missed events.
The only exception is if the event schedule changed and you were unable to make the new time. In this particular case, you can request a refund within 24 hours from the time the rescheduling occurred. After 24 hours, there are no refunds. While we want to be fair to everyone, this 24 hour cut-off is designed to keep the integrity of the event.
