It seems that the post you provided does not contain any information related to maintenance report feedback for a public flat house. The post mentions "hpb" which could potentially stand for "Housing and Public Buildings" but without more context, it is difficult to determine the exact meaning of the term. Additionally, the mention of "orange earphones" and "Mike 19 90" do not seem to be related to maintenance report feedback for a public flat house. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
