It seems that the Twitter post "hyangtogol singapore" does not relate to a maintenance report feedback to a public flat house. The term "hyangtogol" is likely a misspelling or a non-sensical term, and the mention of Singapore suggests that the post is not related to a specific location or issue related to public housing. Therefore, the answer is "relatedness": False, "type": "none", and "explanation": "This is not related to public housing or maintenance issues."
