Good gawd. As I said before, I NEVER, in the last few years, have been bothered by telemarketers. And before that, it was very seldom and only because the previous owner of my new number was listed.
I did not go to extaordinary lengths to make this happen. In fact, it was very simple. I just thought about it before hand, that's all.
Quite simple:
Have an unlisted number.
Never leave the box checked asking if they or all their buddies can contact you about their new great deals when filling out web sales forms .
If you are called, ask to be taken off the list... but what ever you do, do not let them get out their sales speech. If you listen to it, it only encourages them.
Never give out your number to any business if you don't have to.
It's that easy, folks. I am NOT bothered by these people, and you don't have to be either. There is NO reason to restrict other people's liberties, simply because you don't want to make your contact info private.
If you're being overtly bothered by telemarketers, it's because you let your personal info out to every tom, dick and harry that wanted it. That's YOUR mistake, because you CAN stop them.
