Beware - Car Audio Dealers - Amazon Seller

I bought the speakers from this shady company thinking they were a legit, and authorized dealer. Oh how wrong I was, I was wondering why the performance was ******* so much the first few weeks and finally found the weak link; fake speakers. My doors are sealed and sound deadened with two layers of MurderMat, I'm using eKs RCA's from KnuKonceptz and an Alpine PDX-F4 Amplifier tuned with a SMD DD-1. Everything else works perfectly in my system except for these speakers. I swapped speakers for some random Polks I had laying around and they destroyed these Alpines, it wasn't even a competition. I took out my speakers and started doing some initial checks of the product and found quite a few things. While everything looks as it should when powered off (minus the missing serial numbers, oh did I forget to mention that?). When I power them on I hear sound come out but whats the woofer do? Not even flex a millimeter. I turned my HU up to max unclipped volume and are the woofer moving at all now? Nope. Just the same little tiny vibrating, no excursion at all. I looked at some Youtube videos to see if that is just how these speakers are and they are most certainly supposed to be excurding, even on low volumes. I'm contacting my credit card company soon to file a chargeback, contacting Amazon to inform them of fake merchandise and contacting Alpine to inform them someone is peddling fake Alpine gear. I tried contacting the company to resolve this and the manager, William, pretty much told me "You're wrong, we don't sell fake stuff, only brand new A stock from an Alpine distributer" I proceeded to ask him just to tell me the name of where he gets his speakers and he simply told me "That's a trade secret". Seems legit. He then proceeded to tell me to send back the unit and he'll get everything exchanged. I'm extremely skeptical about sending it back(He's making me pay shipping to send back his defective garbage?) because I feel like it's going to end up "lost" or "You sent back a different unit". Some typical run around crap. I gave him an ultimatum and that was to send me a legit set, and then I'll send back his defective fake pieces of crap or I pursue this legally. I've also seen the horror stories on his reviews of refunds taking 3+ weeks to process.

EDIT: Will upload pictures of speakers in about an hour when I take these out for good.
