It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house. The post mentions a business named "Grapevine Café Bar & Restaurant" located in Upper Serangoon, Singapore, but it does not mention any issues or concerns related to public housing or maintenance reports. 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 of the other categories. The "explanation" field provides a brief explanation for why the post does not relate to the topic.
