Guild Wars 2

My brother and I have been playing Guild Wars 2 for a while, but we believe my brother’s account has now been hacked; several days ago, in fact, on Monday the 3rd of September, when he was unable to log into his account, whether through the game client or in the forums.
He has filed a ticket (Number: 120904-010423), but there’s been no reply, so they might have changed his account email address.
He’s trying to chase this up, but we’re finding it hard to find ways to contact Arena.Net. Any help he could get from the community on how to contact Arena.Net, or any support from them on here, would be greatly appreciated!

Hey guys!
