Didn't look at the photo because I don't recognize or trust the site, but in general I'm an advocate of returning things you're not pleased with to the retailer for a replacement. Many retailers will be happy to hand-pick you a knife that has an even edge, good centering, and no mechanical issues, and I generally ask that up-front when I buy a knife online. Don't return knives for warranty service unless you're past the point of returning them to the retailer.
I understand the common refrain that you'll sharpen a knife so you can fix uneven edges yourself, but your time has value (or at least it should), so if you don't want to spend a long time fixing what Benchmade screwed up, I wouldn't blame you at all. That's an expensive knife and it should come with an appropriate edge.
