In a recent entry named “Information Regarding the Cancellation and Rescheduling of Live Events”, Ticketmaster had the following to say:
For future events that are still scheduled, you’re all set. There’s nothing you need to do, and if anything changes, we will contact you with updates.
If your event was canceled, there’s also nothing you need to do. It’s Ticketmaster’s standing policy to automatically refund the full cost of the ticket and fees to the original purchaser’s method of payment used at time of purchase. For any canceled events, due to the unprecedented volume of cancelations, please note that you should expect to receive your refund in as soon as 30 days.
If your event was rescheduled, we are working with the event organizer to identify new dates, and we will contact you as soon as we have confirmation. At that time, if you have any questions or concerns, you’ll be able to reach out to Ticketmaster Fan Support for assistance.
