It seems that the post you provided does not mention anything related to a maintenance report feedback for a public flat house. The post only mentions "Changi Business Park" which is a location in Singapore and does not provide any context or information related to maintenance report feedback. Therefore, the answer is "False" for the "relatedness" field and "none" for the "type" field, and the explanation is a brief explanation of why the post does not relate to the given topic.
