It seems that the Twitter post you provided does not contain any information related to a maintenance report feedback for a public flat house in Singapore. The post simply shares a purchase transaction (buying 11 shares at $11 each) without any context related to maintenance or public housing. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
