Man...this is sad...I hate it when this crap happens. I'm so sorry for you. Unfortunately I doubt you can get your money back but like someone else in here mentioned thank God you didn't buy a bag or something bigger.
You have to exercise great care when you buy from unofficial LV sites. It's always good to request extra pics, if you're not familiar with authenticating yet you can post the pics here in "authenticate this" just to be on the safe side. Regardless of how small the purchase was, it sucks loosing your money like this. I'm so sorry this happened to you.
