spoofing - IRS Scam

Just received a call from a guy who didn't identify himself or the name of the business he was with stating that I owe some quick cash advance place from 2007. He then asked if I received my summons for court yet or if I was aware of what the situation with this "quick cash" was. He then wanted me to confirm the last 4 digits of my social security number and I just hung up.

Got a call and they said there was a case with my name and social security number on it. I needed to call another number. I called them back and there was an answering machine message that did not identify the company and asked for my name and case number. I hung up.
