They left an automated vm saying "don't disregard this call. Return the call before we take any action against you."
When I call back there's no info and it goes straight to vm. Super sketched out by this.

Same thing.

Said they were IRS and to have me or my lawyer call them back.  Do not disregard this message.

Please DO DISREGARD the message.  It is a SCAM.  The IRS mails letters if there is  problem.

It's a scam
