It seems that the post does not contain any information related to a maintenance report feedback for a public flat house in Singapore. The post only mentions "flipper singapore" without any context or additional information that could suggest otherwise. Therefore, the answer is "no" for the question "Does the post relate to a maintenance report feedback to public flat house (e.g., a broken facility, an inconvenience, block number or street, requst fixing, etc.)?"
