Query: Missing Parts

I have had problems with the Serpentine belt for years and saw this solution and ordered it. Got the order and set it on the shelf waiting for a free day to work on it. Opened the box today and there is a tensioner, a belt, and a bolt. No Pulley?!?!?! Also looks like a washer or spacer should have come with the kit. It is hard to know since there is no parts list included. How do I get this problem fixed?
