It seems that the Twitter post "ambush singapore" does not relate to a maintenance report feedback to public flat house. It is not clear what the post is referring to, as it is a generic term that could apply to various situations. Therefore, I have marked the answer as "relatedness": False and "type": "none" as it does not fit into any of the categories provided.
