Replying to I need warranty advice

Last night, my Look Pivot 14's DIN was down at like 4 or something (out of my 8-14 range). I got rental/repairs to tighten it back up to my usual DIN (I think) and I was off on my way. this is the second time it's happened, and they guy recommended I get the bindings warrantied. That would be a good idea, except later that night I flew into a fucking tree and snapped my ski at the toe piece, which may or may not have been because my DIN was too high.

What am I supposed to tell my shop, the truth, or a well constructed lie? I can't afford new skis.

I'll post a picture in a little bit of the skis.

Thanks guys
