If you have changed bank connections after your tickets for a cancelled or moved event were purchased and you are applying for / waiting for a refund, please contact your old bank and inform them that the money has been returned to them. The banks usually collect such cases and will contact customers, but this may take longer. We therefore recommend that you contact the bank yourself.
Unfortunately, Ticketmaster cannot take action in such cases, as the amount has already been reversed and is out of our accounts.
