Claimed that this was 'final notice' from the 'IRS - Internal Revenue Service' that they were suing me.  No statement of previous contacts (there are NONE)...no statement about the claimed issues (there are NONE)...no statement about a case number.  This is a SCAM designed to get callees to panic and call them back. DO NOT DO IT!!  They are NOT the IRS!!!!  SCAM  SCAM  SCAM  SCAM

Claiming to be from the IRS

ditto

I got it about one hour ago. Same message saying IRS is filing a lawsuit against me. When I called back, they claimed they are IRS and asked me to verify a lot of information. It seems to be SCAM. So I hang up.

Received the same message.
