It seems that the Twitter post "tap 9 penang singapore" does not relate to a maintenance report feedback to public flat house. The term "tap" is not a common term used in public housing or maintenance reports, and "penang singapore" is a location that does not provide any context for a maintenance report. Therefore, the post does not match any of the categories in the question.
