I have received countless calls from these fake IRS callers saying they have filed a case against me and I must pay them, blah, blah, blah, that I really do not care any more. So I picked up the phone as the ID said 'wireless caller'. So the usual IRS taped message starts off and I hung up. This number has promptly gone to my call blocked list but these swines keep calling from different numbers. My carrier AT&T does not do any thing about this.!
