It seems that the Twitter post "causeway 0 singapore" does not relate to a maintenance report feedback to public flat house. The term "causeway" is likely a location or a road name, and "0 singapore" is a specific location within Singapore. Therefore, this post does not match any of the categories mentioned in the question.
