It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house in Singapore. The post simply mentions "subway Singapore" without providing any additional context or information. Therefore, the answer is "relatedness": False and "type": "none" as there is no information to suggest that the post is related to maintenance reports or public housing in Singapore.
