You can certainly contact them and politely ask. But there's no guarantee that they'll do anything about it.
As OC said, I'll be a lot less hassle if you just get the parts needed and fix it yourself. While you're at it you could either do as he said and slip a piece of tubing over it to cushion it, or just reroute it to not run across the frame.
