It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house. The post contains the sound of an elevator and the mention of Singapore, but it does not contain any information that suggests it is a maintenance report or feedback for a public flat house. Therefore, the answer is that the post does not relate to this category.
