Blocked this one. I have had the IRS thing before. The IRS DOES NOT call you - they send you a letter. Don't fall for the IRS thing. I have dealt with IRS before so I know this first hand. The sickos on the other end of the line are using a computer generated voice. Do not call them back as they now know your phone number is active. Do not call any of these annoying calls back.
The name on my caller ID came up as "Triangle" . When I answered, it was a woman that said she was taking a poll for a hospital in an area called Polk County. When I told her I've never heard of that county, she said she had the wrong number and rudely hung up on me.
Just got a call from them. It rang three times and they hung up. Caller ID said it came from Triangle, VA - which I have never heard of. Blocked the number.
