If it was the IRS it would say so on you caller ID. When you ask questions they seem to hang up. The IRS will not call you they will send you USPS mail.
Annoying calls from this #..Wish they would get a real job. ..Claiming to be IRS. .& are issueing arrest warrants. .You have to laugh at these people. ...Oh and they have American names but the accent is Indian origin! !
