It seems that the Twitter post "nex singapore" does not relate to a maintenance report feedback to public flat house. It is not clear what the "nex" in the post refers to, and it does not contain any information that suggests it is related to public housing or maintenance report feedback. Therefore, the answer is "relatedness": False and "type": "none".
