Just got a call on my cell a few minutes ago. They did not leave a message. After reading everyone's responses I have blocked this number. I too am on the national "Do Not Call" registry. Must be a scam.
Next time just say calmly, "your [insert loved family member] is going to get cancer and you [insert another loved family member] is going to die in a terrible car accident today"
Just called my cell phone 4 times in rapid succession-- literally 4 calls in 1 minute. Each time my phone rang once, they hung up, then immediately called back. I blocked the number.
