I agree with John. It's a scam intended to get people to agree to move their credit card balance.
But my call started out with a recorded message. I hung up before the message finished the first sentence. The recording made it sound like a legitimate office in a legitimate company. One thing... the recorded voice sounds like the same voice I hear from my friendly Walgreens pharmacy.
I have said this many times on 800 notes with as many phony numbers. IF YOU DO NOT RECOGNIZE AREA CODE OR NUMBER, DO NOT ANSWER -- AND NEVER CALL BACK. Once they make a connection and know it is a viable number, they will sell it to other bottom feeders who are more than likely at a phone bank in a foreign country and you just might be charged for an overseas call!!! The more we ignore these idiots, the better.
