It seems that the Twitter post "good morning duitsg ikan bakar" does not relate to a maintenance report feedback to a public flat house. It appears to be a general greeting in Malay, with "duitsg" meaning "good morning" and "ikan bakar" meaning "fish grilled". Therefore, the post does not match any of the categories mentioned in the question.
