It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The term "rivervale singapore" does not appear to be a specific location or facility related to public housing in Singapore. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" as there is no specific type of feedback or report provided in the post. The "explanation" field is set to a brief explanation of why the post is not related to the requested topic.
