It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house in Singapore. The term "shutters southern Singapore" is quite broad and could potentially refer to a variety of things, but it does not seem to be related to any specific issue or request for maintenance in a public housing estate.
