I come after a very long time without logging. Now I dont have any character.

is your account premium?

on which realm were you playing ?

When did you play last time ?

icecrown.

years ago xD i dont remember

if you can not see them on website, they might still be there but flagged for a rename (due to inactivity).
So, check in-game

If you can not see them in-game (be sure to select icecrown realm) then there is nothing you can do.
you may try to send an email to [email protected] as last chance
