It seems that the tweet does not relate to a maintenance report feedback for a public flat house in Singapore. The term "chill otc singapore" does not provide any context or information that would suggest otherwise. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house in Singapore.
