Called my cell which is on a DNC list. Left no message. Montana call so thinking it might have to do with my relative that died during the night I tried to call the # back and call failed then I tried Google for the # and am glad I didn't get any response.
This call comes from Livingstone, MT. I don't know anyone there, so I don't pick up the phone. They leave no message. They will get tired of calling. Generally, they all get tired when no one answers them. And, I've reported these numbers to the donotcall, gov, and they don't do a very good job of stopping the calls.
If they are really annoying, I block them with my AT&T service which allows me up to 12 numbers to block. When I've had a number blocked for several months, I remove it to replace it with another pesky number.
