It seems that the post does not mention anything related to maintenance report feedback for a public flat house in Singapore. The phrase "transit stage 3 Singapore Changi Singapore" does not provide any context or information that would suggest otherwise. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
