The provided Twitter post does not seem to relate to a maintenance report feedback to public flat house in Singapore. The post simply mentions the date and time (20/21 Singapore) without providing any context or information related to maintenance or public housing. Therefore, the answer is "relatedness": False and "type": "none".
