When the authorization to charge a card is denied, the credit card company
doesn't usually provide a detailed reason. The transaction is simply accepted or rejected.
When it's rejected, it could be because the billing
address/information that was supplied when you signed up doesn't match what's
currently on file at your credit card company; often a charge is denied because there
are insufficient funds/credit remaining on that card's account. Sometimes
it's just a temporary problem, and attempting to charge the card again after
a few hours or days may be successful.
The only thing we can do is try again: if it's just a transitory problem (i.e. insufficient funds), another later attempt may work. Our system automatically retries charging your card a limited number of times over a period of a few days before giving up.
If your account was suspended because of payment problems, you need to get in touch with your bank or credit card company to check if there's a problem, or provide a
different credit card number.
