It seems that the Twitter post you provided does not relate to a maintenance report feedback to a public flat house. The post simply states the time of day (8:50 AM) and does not mention any specific issues or requests related to maintenance or public housing. Therefore, the answer is "relatedness": False and "type": "none".
