It seems that the Twitter post does not relate to a maintenance report feedback for a public flat house in Singapore. The term "fairprice finest singapore" does not contain any keywords related to maintenance or public housing, and does not appear to be a complaint or feedback about such issues. Therefore, the answer is "false" for the question "Does the post relate to a maintenance report feedback to public flat house?"
