It seems that the post you provided does not contain any information related to a maintenance report feedback for a public flat house. The word "treasure" and "tampines" do not suggest any connection to public housing, and "sim lian" is a private property developer and not a government agency responsible for public housing. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
