I bought the wrong thing. Can I change it?

HI GM，I bought the wrong thing. Can I change it?

my game id is Glassfish,is human mage

Just now,i bought the Distant Land Heroic by C,This is a mistake.

This is a very big mistake.

So i hope GM can help me to change this weapon Bloodsurge, Kel'Thuzad's Blade of Agony Heroic

This makes my game normal.

thank you

If you have premium Status and you bought it with coins, you can create a ticket via website, i think it's called Item Missbuy.
