If it's under warranty, get it repaired. If it's out of warranty, consider replacing it instead of paying to get it fixed - it might be money better spent than paying the repair fees.
You've already been without your camera now for 2-3 days at least; if you'd sent it in to K-M to get it repaired they'd already have it in their hands and you'd get it back 2-3 days sooner than you will now.
