You will need to contact Ticketmaster via their help page on this link. There is no additional charge to exchange, and tickets will be allocated in the same price reserve as your existing ticket. On Saturday night we are unable to guarantee the same seat allocation, and seats will be on a first come, first served basis.
Ticketmaster can process your refund. Please submit your request via this link. Note that once your request is processed it can take up to 10 business days for this to appear in your account.
No, there is no need to print new tickets. Your existing ticket/s with the original date will remain valid.
