It seems that the Twitter post "jewel singapore" does not relate to a maintenance report feedback to public flat house. It is not clear what the post is referring to, as it does not provide any context or information about the topic. Therefore, I have marked the answer as "relatedness": False and "type": "none" and provided a brief explanation to clarify that the post is not related to the requested topic.
