It seems that the Twitter post "ooo andaz singapore" does not relate to a maintenance report feedback to a public flat house. The term "andaz" is likely a misspelling or a non-sensical term, and does not convey any information related to maintenance or public housing. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
