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 the location "Sembawang, Singapore" without any context or information related to maintenance or housing. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house?"
