It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The post mentions "grapevine caf bar amp restaurant" in Upper Serangoon, which suggests that it is a business or commercial establishment rather than a housing estate or maintenance issue. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because it is not related to any specific category. The "explanation" field provides a brief explanation for why this is the case.
