Deleted Chars

I recently deleted three characters on my account on the lordaeron realm (Disdemona -warlock lvl 67, Artemisx - hunter lvl 71, Equilibrio - shaman around lvl 60). Now I decided to restore them, because I want to continue playing them. That should have been possible, because two days aren't gone yet. But it was only possible with the warlock. When I tried it with the other ones I got the notification that I haven't enough coines to do so. But coines shouldn't be nessecary and it even worked with the lock as well. I would be glad about support.

Best regards,
Equilibrioz
