It seems that the tweet "nex singapore" does not relate to a maintenance report feedback to public flat house. It is possible that the user is simply expressing their excitement or enthusiasm for something, or it could be a random phrase with no specific meaning or context. Without more information or context, it is difficult to provide a more specific answer.
