It seems that the Twitter post "changi singapore" does not relate to a maintenance report feedback to a public flat house. It is not clear what the post is referring to, as it is a general statement about Changi Singapore. Therefore, the answer is that the post does not relate to a maintenance report feedback to a public flat house.
