It seems that the post you provided does not contain any information related to a maintenance report feedback for a public flat house. The word "yishun" could refer to a location in Singapore, and "emerald" could be a reference to a housing estate or apartment complex, but without more context, it is difficult to determine the specific topic of the post.
