Hello Michael!
I've looked over your report and I've come to the conclusion to deny this.
Doombringer might've taken the warning a bit too early but there are claims you've denied that you broke the rules, you didn't say sorry, and you were arguing back. That's the reason you didn't get unwarned.
The policy specifically states administrators, that means HA and SA supersede that and are allowed to handle any appeal they feel the need to.
