So I called this number back yester from a landline at work and I played their game. I gave them a fake name and a made up zip code and the nice gentleman told me to wait a minute while he pulled my information up. He came back and asked me if i was this "fake name" and I said yes. He told me about a lawsuit filed by the IRS and that they wanted my lawyers information. I asked him how much I owed and he told me that it was $8375.00. I then decided to let him know that I knew that this was a scam and that I was not who I said I was and they need to stop harrassing people with all these phone calls. They called my house 12 times yesterday. He then told me to F OFF and hung up.
