Senior citizens are primary targets of these pests. Please, educate your senior kinfolk and friends to take a second to look at the caller ID. (Let us hope they have Caller ID.) If they see a name and/or number they do not recognize, they should not pick up the call. Thanks.
They have called a couple of times. I add the number to call rejection but they come back with a variation of their number another time. SO, I add them again and will keep doing so until they give up. I called the number and got a VM saying "All our representatives are busy. Please press 5 to be added to our Do Not Call list." I pressed 5 and they thanked me and hung up.
