It seems that the provided Twitter post does not relate to a maintenance report feedback to public flat house. The post mentions "marina bay mrt interchange ns27 ce2 singapore", which is a location in Singapore, but it does not contain any information about a maintenance report or public flat house. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because the post does not belong to any of the categories mentioned in the question. The "explanation" field provides a brief explanation for why the post does not relate to the requested topic.
