Complaint Review: Geek Empire on Amazon

I ordered  World of Warcraft TCG: 2011 Dungeon Deck from a retailer called Geek Empire on Amazon. As described in the introduction, there should be "Total of 3 Different Decks". However, I received only one deck(Shadowfang Keep) and the other two(Scarlet Monastery and The Deadmines) are lost.

I think this is cheating. First, after receiving my package, I have seen many reviews from other customs of the same problem. Second, their price is almost the same as the price for all three decks from the official website.

Also, when I tried to return this just now, I found I cannot return it directly. Maybe, the seller has already known customs will return this item. So they just set this obstacle to continue to defraud.
