It seems that the post you provided does not mention anything related to maintenance report feedback for a public flat house in Singapore. The word "sauna" and "carissa park" do not seem to be associated with any maintenance issues or public housing facilities in Singapore. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
