It seems that the Twitter post "313 singapore" does not relate to a maintenance report feedback to public flat house. The post does not mention any specific issues or facilities related to public housing, and does not appear to be a complaint or feedback of any kind. Therefore, the answer is "relatedness": False, and the type is "none".
