It seems that the tweet you provided does not relate to a maintenance report feedback to public flat house in Singapore. The tweet mentions "sembawang shopping centre" which is a commercial complex in Singapore, but it does not mention anything about public housing or maintenance report feedback. Therefore, the answer is "False" for both "relatedness" and "type".
