Replying to Bad Mount?

Never had a warranty issue with any of my skis before, so thought I'd ask you guys' experience. Been riding my Liberty's for 4 days and had a little crash. Instead of the binding releasing the whole heel came off, I'd say quite confidently that the binding shouldn't have released anyway as I've had similar falls and the skis have stayed on with no probs, with both the Libertys and my old Armadas.

Was just wondering, if it is a bad mount, would I be within my rights to ask for the store to replace the skis as they are only 4 days old, they screwed the mount up and I'm not too happy about the idea of them having to do a re-mount over something that isn't really my fault? Cos surely they'd have the re-mount the bindings further back or forwards and then they wouldn't be in the place I want them...
