It seems that the Twitter post you provided does not mention anything related to a maintenance report feedback for a public flat house in Singapore. The post simply mentions "gocycling east coast park c4 singapore", which appears to be a mention of a location for a cycling activity. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
