It seems that the Twitter post does not relate to a maintenance report feedback to a public flat house. The term "terminal 3 Singapore" could refer to a variety of things, including a transportation hub, a shopping mall, or a specific location in Singapore. Without more context, it is difficult to determine the exact nature of the post.
