It seems that the tweet "koufu kallang singapore" does not relate to a maintenance report feedback to public flat house in Singapore. 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 facility. Therefore, the tweet does not contain any information that suggests it is related to a maintenance report feedback for a public flat house in Singapore.
