USE Alien 8mm Cradle does not fit


I got a Fizik Aliante seat from you and also an 8mm cradle for my USE Alien. The problem is that the cradle doesn't fit the post. It seems that it is a little too big. My post is from 2000, so I'm wondering if they've changed the post somehow since then.
you: Hi
Josh: Well, I have never heard of that problem before. Please give us a call and talk to our customer service department, specifically Dan. He will be able to get that issue ironed out.
you: OK will do I'll ask for Dan.
Josh: Thank you, take care.
