It seems that the tweet "harvest tanjong katong singapore" does not relate to a maintenance report feedback to public flat house. The term "harvest" does not have any obvious connection to maintenance or public housing, and "Tanjong Katong" is a location in Singapore that does not appear to be associated with public housing. Therefore, the answer is that the post does not relate to a maintenance report feedback to public flat house.
