It seems that the Twitter post you provided does not relate to maintenance report feedback for public flat houses in Singapore. The post mentions "new company", "new colleagues", "new challenges", and "Stel train operator", but none of these terms are associated with maintenance report feedback for public flat houses. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because the post does not belong to any specific category related to maintenance report feedback. The "explanation" field provides a brief explanation for why the post is not related to the requested topic.
