robo call to dial back the same number. Called back, started asking probing questions. They hung up. Called again. Started asking the same questions about their agent ID (since I've spoken to actual IRS agents, I know how they answer and the info they always provide). ID was not the same type of number, so I told the guy as much. Hung up again. Called back to talk to a supervisor. Hung up again. Now they are hanging up as soon as they see it's my number. LOL Bunch of f*ing idiot scammers! Unfortunately, they probably ARE getting a ton of money from people who fall for it. I just wanted to see how much of THEIR info I could get from them.
