It seems that the Twitter post "sun plaza singapore" does not relate to a maintenance report feedback to public flat house. It is not a specific location or facility related to public housing, and does not mention any issues or requests for maintenance. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" as there is no other relevant category. The "explanation" field provides a brief explanation for why the post is not related to the requested topic.
