Ok, first things first....I think we all know that these scumbags are just day light robbers and as such there is very little you can now do to get your money back unless the card you used protects you from fraudulent or unauthorised transactions.
The important is to learn from this nasty exprience and move on. In the meantime what you MUST do is to close the affected account IMMEDIATELY and not rely on any refunds, because you are not likely to get it! By all means report it to the relevant authorities but don't wait forever.... before doing something about the affected account. In future when doing shopping on line, make sure that you use a card that can protect you againt fraud.
The US unlike UK has very lax policies on these type of transactions and that is why these scumbags will try it again and again, changing their name even when they get a slap round the wrist. so don't wait ... take action now to protect yourself against any potential future fraud...
