It seems that the Twitter post "serfing singapore sg" does not relate to a maintenance report feedback to public flat house in Singapore. The post does not mention any specific issues or facilities related to public housing, and does not appear to be a complaint or feedback about maintenance. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" as there is no specific type of issue or topic mentioned in the post. The "explanation" field provides a brief explanation for why the post is not related to the requested topic.
