Same experience with me they became vulgar and abusive when I asked more about their claim. I'm calling them back and told them that I would like to make a payment so that I don't go to jail and they hung up. It sounds like a make-shift call center in India.
The Spanish speaking individual states he represents the IRS and that the Sheriff's office will be contacted within 24 hours if I don't call back immediately. They also attempted the same using Phone Number 360-200-0925.
THE IRS DOES NOT CALL PEOPLE ON THE PHONE. THIS IS FRAUD.
