It seems that the Twitter post "ub 1 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 "False" for the "relatedness" field, and the "type" field is set to "none" since it is not possible to determine the type of issue or topic being discussed. The "explanation" field provides a brief explanation for why the post is not related to the requested topic.
