Female with mild Spanish accent (I think) posed as being with IRS threatening legal action.  On call back she answered "investigations dept. of the IRS".  Obvious scam.  No one gets a human when they call the IRS, and they don't call people on phone.  They will ask for your SSN to confirm their information is correct. (They don't have any information.)  I expect what follows would be a most unpleasant surprise.  Number is now not in service, probably throw away cell.  I should have played stupid and given them my exes SSN.

I mean the scammers will ask for you social security number.
