If our system detects suspicious activity on your card, you'll get a text message alert from 37-268 containing details of the unusual transaction. Reply to confirm the transaction. Note that only US phone numbers can receive these texts.
If you report the transaction as fraudulent, you'll receive another message with a number to call to follow-up. Otherwise, no action is required. The system will classify the transaction as "legitimate," and you can go about your business. You'll receive an email notification if you haven't responded to the text.
Lastly, if you can't respond to either the text or email, an agent will attempt to call you on behalf of Natbank to inform you about the suspicious transaction and verify that it's not a fraud case.
