The post does not seem to be related to a maintenance report feedback to public flat house in Singapore. The mention of "hundredandninetynine" and "Singapore" does not provide any context or information that would suggest otherwise. 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 is left blank because there is no additional information to provide.
