It looks like something went wrong.
Please try your transaction again.
Also, verify and make sure:
1. You’re not using a business credit card.
2. You use a card that allows a “cash advance.”
3. Your card details are correct: card number, expiration date, name on card & security code.
4. Your card billing address is correct.
If this is your second attempt and you still get another error message, please create a support ticket by contacting Simplex’s Customer Support HERE.
