It seems that the post does not mention anything related to maintenance report feedback for a public flat house in Singapore. The post only includes a photo of Serangoon, which is a location in Singapore, and does not provide any context or information related to maintenance report feedback. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house?"
