It seems that the post you provided does not mention anything related to maintenance report feedback for a public flat house. The post simply mentions the location "Raffles City Singapore" and the quantity of a product "500ml Singapore Zoo". Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
