It seems that the post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The post contains a photo of Grange Road in Singapore, which is not a location associated with public housing or maintenance issues. Therefore, the answer is "relatedness": False, "type": "none", and "explanation": "This is not related to public housing or maintenance issues."
