Im sure the company that sent you the item, can back-track to where the item came from, where it was scanned, by who etc.
So tell them to start from the begining and they should figure out where this product came from, who was handling it, and if it was, where it was switched for a fakie.
I mean, this is a long shot but... perhaps the real product that you purchased got switched w/ some bunk product in delivery (or before hand)
Either way, the company that originally sent you the item is at fault for your not receiving what you paid for. Take their ass to court and im sure you got a 100% case money back guarantee. [bummer so much time waste] tx for letting us know
hope for the best..
