It seems that the tweet you provided does not relate to a maintenance report feedback for a public flat house in Singapore. The tweet simply mentions "sembawang shopping centre singapore" without any context or details that suggest otherwise. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house in Singapore.
