Call comes at dinner time. Caller ID shows "SPAM". Answer it and no answer/response. Obviously a robodialer trying to see if anyone is home at that time so they can call with some bullshit sales pitch later.
We are on the Do-Not-Call-List but, like every other GOVERNMENT program, has no teeth to it and no one wanting to enforce it. My suggestion is that we develop a way to send a 50-caliber slug over the phonelines to these damned pests. If I am on the DNC List and they make unwanted calls to me, they deserve the "penalty" rendered!!
