Wow. After reading all these comments, glad we missed this call on 2/26/16 while we were on vacation. No msg left; assumed it was a political call. Then, it called again 3/16/16. I picked up and hung up immediately to break the call. It WOULDN'T LET ME! It started ringing IMMEDIATELY again. I did the same thing and AGAIN it just starting ringing immediately. It went to ans. machine, but then failed to leave a message. Scary. Kinda glad I didn't get the message; after a call that wouldn't disconnect, I might have believed it! Have read about these calls, but never got the "IRS" call before.
This 202-249-7466 phone number called my landline at 5:58AM this early morning and left a recording message exactly the same as that from phone number 202-499-1448. The message states "... treasury, this is Officer John Coskin, at the moment you receive this call, you need to call us back at 202-249-7644". Caller ID shows Washington DC.
A recorded message about a warrant for your arrest, from the treasury department. A SCAM CALL. HANG UP! Don't waste your time calling. Reporting this call from PA, USA.
