I cannot reply to ticket after GM request

I’ve come back to WoW retail after a long time (probably more than 15 years) to find my characters missing. I opened a ticket and a week later support found the issue — apparently my old account was compromised, but they’re able to recover my characters to a new account.

Obviously, this is great news! The GM said I should reply to the ticket with a new email address for the account. However, when I try to login to reply, I’m told my account is banned. When I try to go to the account restrictions page, I’m also told to login and am unable to. The account unlock self-service also doesn’t work.

Long story short, I have no way to directly reply to this ticket and have been locked out of playing any game on that account.

I created an non-account ticket about this yesterday but still have no response. Right now, I’m completely blocked from using my WoW retail subscription and I’m also worried about what will happen to the new characters I’ve made using that email address (since there seem to be 2 accounts associated with it??).

Is anyone able to help with this directly or suggest a way I can reply directly to the ticket in hopes of a quicker resolution?

Thank you
