It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house. The post simply mentions "Marina Bay Sands" which is a popular tourist attraction and shopping complex in Singapore, and does not mention any issues or concerns related to public housing or maintenance. Therefore, the answer is { "relatedness": False, "type": "none", "explanation": "This is not related to public housing or maintenance issues." }.
