Help with unlinking steam from recovered compromised account

My account was compromised a few days ago, but I've recovered it. But now i can't play anything as my steam account was unlinked, and the thief's steam account was linked. It says I have to wait 6 months before unlinking the account, which is way too long.

I tried contacting support, but just got an advisor who can't actually do anything. When I tried to contact support again there's no other option besides "contact an advisor" which is now also greyed out.

Is there any way to get in contact with actual support?
