It seems that the post does not mention anything related to maintenance report feedback for a public flat house in Singapore. The post only mentions "posted video east region Singapore" without providing any additional context or information that could suggest otherwise. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
