It seems that the post does not mention anything related to maintenance report feedback for a public flat house in Singapore. The post simply contains a single word "quarantine" followed by some random characters, and does not provide any context or information that could be related to a maintenance report. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
