It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The post mentions "kallang delivery base 18 jalan lembah kallang" which does not seem to be a location or address associated with public housing or maintenance reports in Singapore. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since it is not related to any specific category. The "explanation" field provides a brief explanation for why the post is not related to the requested topic.
