It seems that the post does not mention anything related to maintenance report feedback for a public flat house in Singapore. The post only shows a photo of Kallang, which is a district in Singapore, and does not provide any information or context related to maintenance reports or public flats. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
