It seems that the Twitter post you provided does not mention anything related to maintenance report feedback for a public flat house. The post simply states "day 1 working alone theatre mediacorp" and does not provide any information related to maintenance or facilities in a public housing estate. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
