It seems that the post does not mention anything related to maintenance report feedback for a public flat house. The post only contains a photo of Nanyang Polytechnic, which is a tertiary institution in Singapore. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
