This works for me. I leave my answering machine on all the time and keep my handset within reach (cordless phone) monitor number calling and don't answer. Their computer picks this up and stops dialing that number. Only time it doesn't work is when I have my home phone on forward to my cell which has auto answer feature.
Just a guess; but My [***] does NOT require enhancement; so I say piss on them and all they stand erect for- I'll bet they are flaccid "little squirts", expecting you to swallow their whole "load" down your gullible throat. I say bend them over and drive it home that [***] like them are rubbing us the wrong way.
