It seems that the post you provided does not mention anything related to a maintenance report feedback for a public flat house. The post only mentions the Nicoll Highway MRT station, which is a public transportation hub in Singapore. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
