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.

Received a call, did not answer.  I have the Truecaller app on my phone.  Interestingly, a search on the app links this number to a lawyer in IL.

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.
