It seems that the post you provided does not mention anything related to maintenance report feedback for a public flat house. The term "back time" and "chef" do not seem to be related to maintenance or public housing, and "sixeats andaz singapore" is not a specific location or facility related to public housing. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
