It seems that the post you provided does not contain any information related to a maintenance report feedback for a public flat house. The word "flamingo" is likely a location, and "siglap" is a street in Singapore, but there is no mention of a maintenance issue or feedback related to a public flat house. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
