Left me message saying they were from Wildfire Fraud Protection. They had the last 4 digits of my credit card number. I called Wells Fargo Fraud Dept; turns out, someone charge $1, apparently seeing if the charge would go through. Cancel card with WF. Afterwards, I call the number and the message was for a Cisco answering service. That's when looked up the phone number online. It felt very wrong, so BEWARE.
