If you did not receive an order confirmation email, the charges have been blocked due to fraud prevention. This error comes up when either your billing address, zip code and/or cvv do not match.
Depending on the type of card being used, you may see the card issuer's authorization for the payment amount on your statement. This amount has not been charged and no funds have been taken. The authorization is removed from your statement by the card issuer within a few days.
Check your card details and try again.
