Bought the wrong item

I accidentally bought Havoc's call, Blade of Lordaeron Kings (Heroic) for 23 coins on my shadow priest. In game name Xarpo.

Im so sorry to waste your guys time but is there anyway I can get a refund or swap for Royal Scepter of Terenas II (Heroic)

I havent opened the mail yet, it says #22387593. I currently have an open ticket as well.

Thank you,
