It seems that the Twitter post "muster5 pc jk singapore" does not relate to a maintenance report feedback to a public flat house. The term "muster" is likely a misspelling or a different term altogether, and "jk singapore" does not provide any context or information related to maintenance issues. Therefore, the answer is "relatedness": False, and the type is "none".
