Hi there,
Account surrender means the seller has setup an account that houses the tickets, they would then provide you with the login credentials and you would need to login to the account to view and access the tickets using the login credentials from the seller. It is a valid and safe form of delivery and only used when the event organizer has turned transfers off for that particular event.
All sales are backed by our Buyer Trust Guarantee so even with Account Surrender orders, your order is safe and protected by our guidelines.
