I recently sold tickets to a concert occurring on December 28th and I listed that the person will receive the tickets on December 21st. Apparently there is a hold on the event and the tickets won't be lifted until December 23rd at 9am. The latest I can change the date for the person to receive the tickets is on the 22nd. How can I change the date to the 23rd? I need to change the date asap. Thank you!
