It seems that the post does not mention anything related to maintenance report feedback for a public flat house. The words used in the post, such as "silence", "gold", "happysunday", and "city hall" do not suggest any connection to maintenance or infrastructure issues. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
