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", which does not provide any context or information related to maintenance reports or public flats. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house?"
