It seems that the Twitter post you provided does not relate to a maintenance report feedback for a public flat house in Singapore. The post simply mentions the general location of a post office in Geylang, Singapore, without any indication of a maintenance issue or feedback related to public housing. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because the post does not belong to any of the categories mentioned in the question. The "explanation" field provides a brief explanation for why the post does not match the given criteria.
