A pre-recorded woman's voice calling from "Customer Service" (no company name given) to let you know that your "Preferred Customer Status" is about to expire and that she sees a "Credit" on your account for a free cruise and wants to help you get it applied to your account before you lose your status. Then the pre-recorded voice says she just needs to verify your information so she can help you get the credit applied.
Basically, this is just another phishing scam. They are just trying to trick you into giving out your personal info so they can record it and use it for identity theft. Number blocked.
