It seems that the provided Twitter post does not relate to a maintenance report feedback for a public flat house in Singapore. The post mentions "greenwood sanctuary admiralty singapore", which could be a location or a park, but it does not contain any information related to maintenance reports or public housing. 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 of the categories mentioned in the question. The "explanation" field provides a brief explanation for why the post is not related to the topic.
