For anyone who isn't happy with the tickets that they purchased or mistakenly purchased tickets they didn't want: when I bought my tickets, I noticed that there was something called a "Free Looking Period" before I entered my payment details. There was a statement that said that tickets could be refunded within 10 days if they were not to the customer's liking.
Doing an online search for "Ticketmaster free looking period" yields hardly any results (and the one result looks like it's a contract that is more detailed than Ticketmaster let it on to be). Maybe try researching the free looking period to see what you find?
EDIT: My tickets were official platinum. Not sure if that makes a difference or not.
