Be smart. Google any phone number you don't recognize before you call it back. This one is a telemarketer about vacations. It will also give you the option to be removed from their call list. Don't do it. You can block this number on your cell phone.
Call came in this morning, 07/20/2016, with the usual Unavailable ID. I did not answer the call, since I never answer such calls, but I did listen to the message that came on: "Do you see Donald Trump as your President, push one for yes, or two for no?" The public will be inundated with these types of political robo calls, until after the election. A sickening thought.
