The post "jewel singapore" does not seem to be related to a maintenance report feedback to public flat house. It appears to be a mention of a shopping mall in Singapore called Jewel Changi Airport. Therefore, the answer is "relatedness": False, "type": "none", and "explanation": "This is not related to public housing or maintenance report feedback."
