Same as above, left message that said tax fraud claim against my name - not identifying me - and that i would be arrested if i don't call the number. Ignoring it!
I got the call from this number today, but was not at home. They left a message on my answering machine. Thanks for all the info given here. I have sent an email to the IRS and filled out a complaint form with TIGTA and I also filled out a complaint on the Do Not Call list.
