I once asked a telemarketer for their name, phone number and address. When they said they could not give me that information I said it only seemed fair as they knew mine. then I hung up. I'm with all of you who use the answering machine, number ID on cell, etc. I just do not want to hear bout prostate cancer, hearing aids or pre-planned funerals while eating my supper.Keep on with the do not call preventives often.
