Pretty much the same as other posters. I'm writing this so that maybe somebody somewhere is reading this and taking notes and just maybe willing to actually DO something to help get rid of this mess.
Keep getting these calls, and continue to report them immediately as they come in to donotcall.gov. I've been advised to not respond to these types of calls (including any engagement with the operators or even any kind of request to be removed from the call list), but I'm hoping that constant reporting will eventually make these callers stop.
Here, too. ALL it said was "press 9 to be put on the do-not-call list." No other words and no human. I only disconnected and will now block. Thanks, everyone!
