It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house in Singapore. The post mentions a business named "Grapevine Café Bar & Restaurant" located in Upper Serangoon, but it does not contain any information about a maintenance issue or feedback related to public housing. 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 contains a brief explanation for why the post is not related to the requested topic.
