Query: poor shipping package

The product came in a loose envelope. The paper box of the item is not sturdy enough to protect the plastic material of this product. A small piece of plastic has been broken. Even though the item is still functional, I am very unhappy with the vendor who did not ship the product in a sturdy box. The sucking cup is pretty strong, after several weeks, it still hanging strong on the window.
