Sign up with the National Do Not Call Registry.
We did and it has cut down tremendously on unwanted nuisance calls.

Now, if only the blastingly LOUD once a day calls telling us we've won a home burglar alarm system would stop calling..........its a recording, thus we cannot tell the caller to stop.

However, the National Do Not Call Registry does solve the problem for several years; then you have to register again, which we just did. If they persist in calling, tell them it's a big fine to do so........that usually works..........if it is a HUMAN on the other end.

p.s.
Although it says it does not expire.......ours apparently DID do so after about three years.........so we just signed up again and it has tapered down a lot.
Not sure, but guess it takes awhile for these rotary dialers to "get the message". Good luck everyone. Those calls are annoying, to say the least.
