WagJag is by far the worst of the group-buying websites. Google them and you'll find their most common scam is to double-charge your credit card.
Try and call them to resolve the issue and the person you speak to acts like they can't do anything and tries to be sarcastic to you like you're being unreasonable. When I buy something and in return I have money stolen directly from me, I consider that a breach of trust. They think if they make it difficult for you you'll just forget.
The Toronto office has the most evil people answering the phones. If you live in Toronto do not give any credit card to WagJag.
