It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house in Singapore. The term "greenwood sanctuary" and "admiralty singapore" do not appear to be associated with any specific public housing estate or maintenance issue in Singapore. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house in Singapore.
