I would definitely push them to give you your money back.  Really, when you look at it, all you have is a high-priced piece of plastic since it isn't any good for typing.  I would get your money back, and find a proven winner (Model M, CVT Avant Prime, HHKB, etc.).  If they decide to recall/fix the Das III, and the blue Cherries are your thing, then, maybe, give them you business again, but until then, I would look to get a refund (and push them to pay for shipping, especially, if you had to order from the US).
