It seems that the Twitter post "ouch singapore" does not relate to a maintenance report feedback to public flat house. It is not clear what the post is referring to, and it does not contain any specific information or context that would suggest otherwise. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house?"
