Query: Missing pieces!!

My bird feeder arrived today. I was excited to get started, however, when I opened the box, it was all in pieces and was missing the suction cups and "back piece" that the suction cups were supposed to snap into! It is completely worthless and unusable. I can't really rate the actual product since I can't use it, but the company I placed the order with will be receiving my complaint soon. Very disappointed.
