It seems that the Twitter post you provided does not mention anything related to maintenance report feedback for a public flat house in Singapore. The term "east coast ngoh hiang" is likely a reference to a type of Singaporean dish, and does not pertain to any maintenance issues in public flats. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
