It seems that the provided Twitter post does not relate to a maintenance report feedback to public flat house in Singapore. The post mentions "greenwood sanctuary" and "admiralty park singapore", which are likely locations or landmarks in Singapore, but there is no mention of any maintenance issues or feedback related to public housing. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since 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.
