Just for clarification, while you may not have received an email on the final screen, when you submit a ticket should provide the summary of your ticket and the ticket ID. If it does not, you may not have successfully submit the ticket.
I wouldn’t be able to see the first ticket without the ticket ID, but I can see the one you submit under this Battle.net account. From what I can see the entity that compromised the account appears to have gotten caught, so the account is currently closed.
The compromise investigation, once they get to your ticket, should allow them to verify the compromise, overturn the action, repair what damage may have happened at the time and return control to you.
Be sure to add an Authenticator when you regain control, that should help prevent this from happening again.
