It seems that the post does not mention anything related to maintenance report feedback for a public flat house. The post only mentions "bigbrand satay" without any context or information related to maintenance or public housing. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since the post does not fit into any of the other categories. The "explanation" field provides a brief explanation for why the post does not relate to the requested topic.
