It seems that the provided Twitter post does not relate to a maintenance report feedback for a public flat house in Singapore. The post mentions "greenwood sanctuary" and "admiralty park singapore", but these are not specific terms related to maintenance reports or public housing in Singapore. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house in Singapore.
