They call often and at early hours, even on weekends. Last time I picked up and the guy asked for someone who no longer lives here and he said he would enter my number for that person as a no good number. That doesn't mean they won't call me. I know you can block 800 numbers with *77 but it seems to also block some of my friends on their cell phones and one relative that has an 800 number. Just let the answering machine get it. These folks are not as obnoxious as those who want to sell me a car warranty and just keep talking into the machine; or the ones that want to help me with my credit (no thanks!). Gee I already dread the next political season. Those are the worst!
