It's four spokes, man.
i mean, sure... you deserve to get the wheels you ordered, but shipping back some dp18's and getting your credit card company to strong arm him sounds like a quick way to draw this thing out for a month or two.
especially because your credit card company could go after you if you did that. but even if you got your cc company to do this and you shipped the open pros back properly and had the cc company do it right, they are doing international business and i'm not sure av here is imparting to you just how difficult they might make it.
this is throwing good money/time after bad.
it's four spokes, just deal with it unless you can't, in which case, yeah av's CC customer protection avenue is probably the right course of action. definitely better than my 'litigation' rec.
but really, four spokes man. get a magic eraser and takethe origin 8 logo off the hubs and then drop this whole thing.
