I'm very sorry to tell you this, but feedback isn't moderated. This means that, unless you're talking about feedback spam, the administrators won't help you.
I don't like it either, but that's just the way it is i'm afraid.
Luckily for you, it were 2 red-tagged non-DT members that gave you some feedback, so it's probably not that important when you look for trades on the forum.
Umm, too bad. I never did anything bad so i don't have to worry.
It's alright, But it makes my Trust Wall look bad. :/
