It seems that the Twitter post "ps cafe singapore" does not relate to a maintenance report feedback to public flat house. It is not clear what the post is referring to, as it is just a simple mention of the name of a cafe in Singapore. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
