First, review your credit card information and make sure it is correct. If you're still receiving an error message after reviewing your credit card information and billing and shipping address, ensure you are using your web browser's latest version. Also, make sure you have international and internet use enabled by your credit/debit card provider (we process orders in euros, €), a sufficient amount of funds to complete the purchase, and the same ZIP code in your billing address as with your credit card provider. If your payment still won't go through, we recommend using PayPal to complete the purchase. If you continue to receive error messages, please get in touch with our customer support at support@classywomencollection.com. We will never charge your card if your order doesn't go through.
