It seems that the tweet "welcome jungle singapore" does not relate to a maintenance report feedback for a public flat house. It appears to be a nonsensical statement, as Singapore is a city-state and does not have a jungle. Therefore, the answer is that the post does not relate to a maintenance report feedback for a public flat house.
