It seems that the Twitter post "sundate east coast park" does not relate to a maintenance report feedback to public flat house. "East Coast Park" is a location in Singapore, and "sundate" is likely a misspelling or a slang term that does not have any specific meaning in this context. Therefore, the post does not fall under any of the categories mentioned in the question.
