If you ask them at least three times to put you on their do not call list they have to do it or risk a fine. I don't hang up because they put you right back on the list as a no answer. If it's a recording I will listen for the option to get off their list. This is after many years of doing everything you all have done with no results. I'm getting fewer calls now. I'm not rude when talking to them because I don't want more phone calls as a retaliation. They will call you more if they think you're really annoyed. This method is what the telemarketers have posted as the way to get off the lists. I do think it's working. Just crazy that we have to go through that.
