It seems that the tweet you provided does not relate to a maintenance report feedback for a public flat house in Singapore. The tweet simply mentions "national university singapore nus singapore", which does not contain any information about maintenance reports or public housing. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
