My sister received one today claiming she was a tax evader, etc. It wasn't a good day so she replied, "You lard ass piece of sh*t, I'll tell you what you can do..." Well, she couldn't since he hung up on her, so she dialed back and got a woman, who just answered, hello, then tried to continue the scam. My sister continued on the same vein, and she hung up on her. As my sister views this as a release, she called back again and they disconnected the line. She's had scammers block her. She says she doesn't want to yell at her partner, so she takes it out on them. Just remember, the IRS never phones, it's always snail mail.
