"And seven. I repeat it's 2025172977. The issue is very time sensitive. So before I take any legal action against your name. Call IRS as soon as possible."

Yup, IRS scam. The IRS WILL NOT CALL YOU ANT THREATEN TO TAKE ACTION AGAINST YOUR "NAME". If the IRS needs to speak to you they will send you a notice in the regular US mail. This number called me May 16, 2014

Same old IRS scam from India. DO NOT talk to them, hang up the phone immediately.
