Question about "merge"

Hi there. I'd like to ask where can I seek help regarding merge.
On "My Account" page it says my character was merged and transferred to Icecrown but it's nowhere to be found when i log in. Can anyone give some advice on what to do/who to ask for help?
I haven't played on this server in a while so i missed the whole merging of realms thing and I'm clueless at what happened, what was transferred and what not. I'm only asking this because my brother had a warrior on his account and it transferred with no problems("My Account" page says the warrior was transferred, and warrior was there when he logged in).
