It seems that the tweet "cave singapore" does not relate to a maintenance report feedback to public flat house. It is not a specific issue or complaint about a facility, inconvenience, block number, or street, and it does not request fixing or resolution of any kind. Therefore, the answer is "relatedness": False, and the type is "none".
