had this same message/issue a few minutes ago...panic response despite nothing I know of to cause this...

so...I called back and reached a foreign-accented man who informed me that this was "a crime investigation office of the IRS" and hung up on me.

It's an IRS scam. They called me yesterday and I blocked them. They called me today and left same message as you. I couldn't pass up the fun so called them back. Some guy with slight Indian accent answers. I told him to bring it on MFer. Called his mother names, called him names and told him BRING IT ON!  Also told him he's been reported and everyone knows it's a scam. He asked if I wanted to add anything else. Called him a few more choice names, (witch with a b) cussed him up one wall and down the other to a fair thee well. He finally hung up. If they call again they will get more of the same. Don't let them scare you. It's a SCAM.

Have been called by this number for the last 3 days. Robot call trying to scam. Personally know the Feds or the IRS would not call about matters. Do not give personal information or financial. Hang up. They are scammers!

Awkward! Recorded message with British accent says, calling from IRS Regards Federal Charges??? Against me?
