OP, look out for a PM shortly so I can confirm your info and get this issue resolved, and provide you with my direct contact info in case you need to follow-up.
Upon first glance, it does seem that the return was processed improperly. I am following up with our warranty manager to confirm this. More troubling to me are the issues you had dealing with our customer service department; as frustrating as it can be to blow a tweeter, I know that it can be infinitely more frustrating to deal with the "run-around" that it seems you were given. This is the first I've seen of this, so I can't give you a better resolution at this moment, but please rest assured that this is sincerely my #1 priority until it is resolved.
(I fully agree that the location of the "Authorized Internet Dealer" can be a bit misleading, although the specific information about the product's warranty policy/provider are contained in the product description. We are working on some aesthetic changes to the site that will prevent such a misunderstanding from recurring.)
Sincerely,
Daniel Z.
