It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The term "esplanade xchange singapore" does not appear to be a specific location or facility related to public housing, and does not contain any keywords related to maintenance or feedback. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house?"
