It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The post mentions "skytrain station c singapore", which is a location in Singapore, but it does not mention any specific issue or feedback related to public housing or maintenance. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because it is not related to any specific category. The "explanation" field provides a brief explanation for why the post is not related to the requested topic.
