It seems that the Twitter post does not relate to a maintenance report feedback to public flat house. The user's handle "tamil tech karthik" does not provide any context or information that suggests otherwise. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since the post does not belong to any specific category. The "explanation" field is left blank since there is no additional information to provide.
