It seems that the Twitter post "coastes singapore" does not relate to a maintenance report feedback to public flat house in Singapore. It is not clear what the post is referring to, and it does not contain any information that would suggest it is related to public housing or maintenance issues in Singapore. Therefore, the answer is "False" for both "relatedness" and "type". The explanation is provided as a brief explanation for why the post is not related to the requested topic.
