It seems that the provided Twitter post does not mention anything related to maintenance report feedback for a public flat house. The post simply mentions the name of a food product (coconut ice cream) and a person (Violet Oon) in Singapore. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
