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 various things, including an airport terminal, a transportation hub, or a specific location in Singapore. Without more context, it is difficult to determine the exact meaning of the post.
