I received the same call from this number. He told if I don't give him the info he's going to get arrested within 72 hrs. he hung up after I told him I'm calling the IRS to confirm.
A gentleman called me stating that I owed money on my taxes from last year and then I had already received notification via the mail. I asked him for his qualifications and he got very upset and irate and quite frankly insulting and unprofessional. This is totally a scam.
Exact same thing happened to me. Threatened to send authorities to my home and arrest me. Somehow they have name home address and all. I guess that wouldn't be too difficult with the internet and all. Sounded like the voice of the caller was being altered as well.
