Can i recover deleted characters?

So the other day, my little brother thought it would be funny to delete all of my characters on my account while i went AFK to get some food,

As you could imagine i was furious!!! is it at all possible to have these characters restored? All characters were on Icecrown Server

They were:

Beebopp - Lvl 42 Orc Hunter
Rustyspoon - Lvl 41Belf Paladin

and a few others >lvl 20 that i dont care so much about,

All up i had roughly 60g.

I dont know if this is the correct place to ask this type of question or not.. feedback will be very much appreciated
