The given Twitter post does not relate to a maintenance report feedback to public flat house. The post is about a personal experience of attending a classroom since a long time and the first day of school for primary one in Singapore. It does not mention any issue or inconvenience related to public flat house maintenance. Therefore, the answer is "False" for the relatedness and "none" for the type, along with a brief explanation.
