It seems that the post you provided does not contain any information related to a maintenance report feedback for a public flat house in Singapore. The word "katamad" is not a term commonly used in Singapore, and "crayfish" is not a facility or infrastructure related to public housing. Therefore, the post does not meet the criteria for a maintenance report feedback.
