Robo dialer.  When answered a real person came on the phone asking to speak to the owner, which I am.  Said he was from Nationwide and that our business liability insurance was about to expire.  I told him I did not think we had our liability insurance with Nationwide.  He said no you don't but I think we can beat the rates you are now paying. . . .  Ask how did he know that our existing policy was about to renew.  Said he was not "100% sure but could beat their rates."  Told him we did not do business that way and to please not call back again.  Number blocked.  Maybe I am just too much of a stickler for truth, but if the initial approach is underhanded and unethical, then I am not interested in hearing any more or dealing with them.
