It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The term "Oppo" is likely a reference to a brand of smartphone, and the post does not mention any specific issue or problem related to public housing or maintenance. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because the post does not fit into any of the categories provided. The "explanation" field contains a brief explanation for why the post is not related to the topic.
