It seems that the tweet "koufu kallang singapore" does not relate to a maintenance report feedback to a public flat house. The term "koufu" is not a recognized term in Singaporean English, and "kallang" is a district in Singapore that does not refer to any specific public housing estate or maintenance issue. Therefore, the post does not meet the criteria for a maintenance report feedback to public flat house.
