    ]

It seems that the post does not mention anything related to maintenance report feedback for a public flat house. The post only mentions "Lucky Plaza" which is a popular shopping mall in Singapore, and does not provide any context or information that would suggest otherwise. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house?"
