It seems that the Twitter post you provided does not mention anything related to maintenance report feedback for a public flat house in Singapore. The term "blue bottle" and "cousin gang" do not seem to be related to any specific issue or location, and the mention of Singapore is not enough to infer that the post is about a maintenance report for a public flat house in that country. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
