We simply never answer the phone for a number we don't know and they will not leave a message, so whatever they want, they are not going to get.
Their number is now blocked, so I won't have to worry about them calling again, but if they do, I have a program for my computer called PhoneTray Free. If you have a CALLER ID modem with voice, you can set it to any number you like and it will give them a message and hang up.
It's nice if you use the ones with the three tones saying the number has been disconnected.
lol It will also pop up on your computer screen who is calling and keep an unlimited call log. I'm not advertising for this product because it's free with no ads or anything, I just love the program!!!
