It seems that the post "till fat lady sings cb till toto bbt closed" does not mention anything related to maintenance report feedback for a public flat house. The phrase "till fat lady sings" is a common idiom that means "until something happens" or "until a particular event occurs," and "toto bbt closed" is likely a reference to a specific event or situation that is unrelated to maintenance report feedback for a public flat house. Therefore, the post does not relate to the specified topic and is not a maintenance report feedback.
