If you can't log in to your Festicket account, and you need to change your email address, not a problem! We'll be able to change your email address so that you can access your order page. We'll have to carry out some security checks to make sure it is you. These have to be completed via email, so we have a written record. Please submit a support ticket with details of what you ordered and your order number if you know it. We'll help you from there.
