There could be several reasons for your card being rejected.

The first thing you should do is make sure that your balance is not over your credit limit. You may verify this by accessing your Online Account or by calling Cardmember Services.

If your balance is less than your credit limit, your card may be blocked temporarily for security purposes, if the transaction differs from your usual spending pattern.

Please call customer service when you are unable to use your card. We will reactivate your card shortly after we have verified that the transactions were made by the correct card member.
