It wasn't the first time that CapitalOne had shut off my card after a single suspect transaction. But, I'd actually purchased from ClearTrip.com using my CapitalOne card on two prior occasions. It was an example of very poor fraud detection and led me on a tour of their pathetic customer service. The banks want to cut their losses regardless of how it impacts their customers. Having had my own credit card suspended out of an abundance of caution on a different credit card issuer's part (for legitimate charges), but having recently had some widely known scam charges get accepted, the fraud protection algorithms that the credit companies use certainly seem inscrutable sometimes, and so do the surrounding practices about communicating with customers. How would you like it to work instead?
