Refund policy is set by the Organizer of the event for which you registered, so policies will vary from one event to the next and you'll probably have to contact the event Organizer.
The refund policy for your event is available in a few places:
If you still have questions or need to cancel your ticket, event Organizer information is displayed on the right hand side of the Event Registration page. (see image)
Our team at My Event Guru likes being helpful, but all ticket refunds are at the sole discretion of the Organizer for your event. My Event Guru is neither authorized to process refunds to registrants, nor do we set policy for individual events.
