Characters missing

All my toons have disappeared and im confused how to open a ticket. this happened yesterday but still all my toons are gone and want them back

Hi :

Your web profile has only one hero on it… a level 4 (504) wizard… as if all the other heroes had been deleted. If only one hero was deleted, you can undelete it by clicking on Switch Hero on the main menu and clicking the undelete arrow at the left of the Delete button.

You can contact the Account section of Blizzard Support here:

Fill-in the Description box and provide as much details as possible… then click Submit. Blizzard will send you an e-mail when they have replied… with instructions on how to access their reply.
