I couldn't able to merge my characters from Deathwing to Icecrown!

Couple days ago I opened my old account and I didn't find any of my characters I used to play with, but then I realized that there was a merge last year... Is there a way to move my characters right now again? I want to move my characters from Deathwing into Icecrown, you can check my account's log and you will see that I had three characters level eighty on this exact account.

Ragnaros and Deathwing have been merged into 1 realm: Icecrown.
Players had 1 years of time to move their characters to the new realm.

it should be too late to recover your old chaarcters but you may try to contact [email protected] as last chance ( or opening a ticket on website if you are premium)
