It seems that the Twitter post "causeway 0 singapore" does not relate to a maintenance report feedback to public flat house in Singapore. The term "causeway" is likely a reference to a road or highway, and "0 singapore" is a location identifier, but it does not provide any information about maintenance report feedback or public housing. Therefore, the answer is "relatedness": False, and the type is "none", with a brief explanation of why it is not related to the requested topic.
