The post does relate to a maintenance report feedback to public flat house as it mentions "18th weekly craves draw" which is likely a reference to a maintenance report or feedback system for public housing in Singapore. The mention of "50 dining vouchers" and "giving 50 cash dining vouchers" further supports this conclusion. Therefore, the answer is "True" for the "relatedness" field, and "maintenance" for the "type" field, with the explanation being "broken facility (dining vouchers)".
