It seems that the tweet "cmb grams singapore" does not relate to a maintenance report feedback to public flat house in Singapore. The term "cmb grams" is likely a misspelling or a non-sensical term, and does not appear to be related to any specific topic or issue. Therefore, the answer is "relatedness": False, and the type is "none", with a short explanation of "This is not related to public housing or maintenance report feedback."
