who are you?

I recieved a call from this number today. I didn't answer the call, but they left a message. "This is Jennifer with 'ARR' calling for ____ _____ in reference to your account. You need to call back immediately so that we may discuss what to do about your account." SCAM!

I received a call from this number and it shows private on caller ID.  When I returned the call, they do not answer their phone with a business message...it was just a simple "hello".  I asked who I was speaking to and a female asked who I was and I told her that I had a phone call from her number.  She replied that she needed my name and number before she could tell who she was.  I finally told her my number, then she asked for my name....then she wanted me to verify my date of birth.  She was getting angry with me because I would not verify my date, etc.  This has to be a scam!
