Wrong weapon received from marketplace (Onyxia)

Hello,

I purchased the item “Mutilador del Gladiador Mortal” on the Onyxia marketplace because the website listed it as a main-hand/right-hand weapon.

After receiving the item in-game, it turned out to be off-hand/left-hand only.

I would like to request an exchange for the correct main-hand version or a refund if possible.

The website description does not match the item received in-game.
