It seems that the Twitter post "price checker ubk sg" does not relate to a maintenance report feedback to public flat house. It is possible that "ubk" is an abbreviation for a different term or entity, or that the post is unrelated to any specific topic. Without more context or information, it is difficult to provide a more specific answer.
