My called ID says they called 4 times today. Answered last call. They asked for Miss Walker. I said I've told you before there is no Miss Walker lliving here. She said she hadn't called this number today. She hung up. I called back - it's a dissconnected number for Verison. They just called back again - 5 times in a day.
<When I answered< That right there is an invitation to continue calling. Numbers that have any kind of answer at all times will be the ones they'll keep bothering at ALL TIMES. No kind of answer at all can chase pests away and keep your number from being passed on as one to call. Let your phone ring clear through if possible and anger unwanted callers eventually.
