The Twitter post does not seem to be related to a maintenance report feedback to public flat house. The mention of "blk 818a keat hong mirage" does not provide any context or information that suggests otherwise. 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 is left blank because there is no explanation for why the post is not related to the requested topic.
