Event organizers set their own refund policies. Before trying to request a refund, check the event details page or your ticket order to see if the event organizer has set a refund policy. If no refund policy has been set, you should contact the organizer directly. You can find the organizer's email in the organizer's profile page.
Note: If the ticket was ordered by someone else, only that person can request a refund. Contact the ticket purchaser and direct them to follow these instructions.
