It seems that the Twitter post "free test kit haha jurong island" does not relate to a maintenance report feedback to a public flat house. The post does not mention any specific issues or concerns related to housing infrastructure, such as broken facilities or inconveniences, and does not provide any information about a particular block number or street. 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 maintenance report feedback.
