It seems that the post does not relate to a maintenance report feedback to public flat house. The term "bukit merah" is a location in Singapore, and it does not mention any specific issue or problem that would indicate a maintenance report. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
