It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house in Singapore. The post mentions "kovan heartland mall singapore", which is likely a reference to a shopping mall in Singapore. Therefore, the answer is "False" for the question of whether the post relates to a maintenance report feedback for a public flat house.
