The provided Twitter post does not seem to be related to a maintenance report feedback to public flat house in Singapore. The post simply mentions "ngee ann city singapore" which is a location in Singapore and does not contain any information related to maintenance report feedback or public housing. Therefore, the answer is { "relatedness": False, "type": "none", "explanation": "This is not related to public housing or maintenance report feedback." }
