To answer your original question though, a UM has the authority to decide when a subject is done and to close a thread.
Your next step would be to take your complaint to @Chatmaster as instructed by @TheLeigh and I'd strongly recommend you take that option rather than keep opening new threads about the same thing. That can lead to a forums ban if you push it to far js.
Up to you now
