It seems that the tweet "knock knock cafe singapore" does not relate to a maintenance report feedback for a public flat house. It is possible that the tweet is about a cafe or restaurant in Singapore, but it does not contain any information or context that suggests it is related to maintenance report feedback for public housing.
