It seems that the Twitter post "savage singapore" does not relate to a maintenance report feedback to public flat house. The post does not mention any specific issue or problem related to public housing, such as a broken facility, inconvenience, or request for fixing. Therefore, the answer is "relatedness": False, and the type is "none".
