It seems that the Twitter post does not relate to a maintenance report feedback to a public flat house. The post mentions a business, Grapevine Café Bar & Restaurant, located in Upper Serangoon, Singapore, but it does not mention any issues related to public housing or maintenance. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because the post does not fit into any other category. The "explanation" field provides a brief explanation for why the post is not related to the requested topic.
