Replying to Issues with Rossignol FKS

Bought a pair of Rossignol FKS bindings this past weekend and had them put on my skis, I have been on them twice now with no real crashes and no ejections from the bindings and the mechanism that springs the breaks down has already broken (I stepped out of them at the end of the day today and the breaks were just floppy). Seriously this shouldn't be an issue with a $300+ set of bindings with normal wear and tear. Anyone else have issues like this with these bindings?
