It seems that the Twitter post you provided does not mention any specific issue or feedback related to a maintenance report for a public flat house. The post simply mentions the location Keppel Marina, Marina Bay, and My Singapore, which are all locations in Singapore. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
