It seems that the post does not contain any information related to a maintenance report feedback for a public flat house in Singapore. The post only mentions "posted photo Changi Singapore" without providing any context or details that would suggest otherwise. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
