I also got a call from this number saying he was from IRS. He left a voice mail saying I am in trouble. I called back and no one answered. It is a spam! dont give any of your personal information. Most likely these people are calling from a different country trying to steal money. The guy had an accent as well.

I gave my number once at Six flags for some drawing and since then I started getting telemarketers and all sort of spasm. I think my only option is to change my number :(.
