Well buyer beware is how I see it. It's unfortunate when these things happen but they do happen and you shouldn't buy online without proper research and security. There has been plenty information on almost all forums that advised against doing business with this vendor but I guess some just can't pass up on $10 frags, you get what you pay for and ignorance doesn't get you anywhere. If you received a shipment paypal won't help you, not sure about VISA either.
Sorry if it's a little harsh but a lot of people are complaining about this lately and I just laugh when I see the complaint thread and group order thread on the top of the active thread list
The damage is done, move on and take the lesson with you.
