robo call, left msg on my answering machine,  pretending to be the IRS, said they were going to bring a lawsuit against me. blocked their number.

same as above, mechanical voice claiming to be the IRS

Same as above, they called at 6:00 this morning, also called a couple of days ago.  I know it is a scam.

I just came home to this call on my answering machine and will now procede to report them to the IRS and sheriff's dept. thanks for the info, this is a long distance # and i'm wondering if they want you to call back and they are in another country and will charge you outrageous money per minute to talk to them?

This number has been calling my cell phone every day saying they are from the IRS. I finally called them back from another number and when I started questioning the Indian sounding man, he hung up without saying a word. The IRS should investigate this.
