This is an autodialer - the caller ID at my office came up as McBlue Telecom, and it was a recorded message that says to update your google listing you should press 1, to remove your name from the calling list, press 2. It will go on and on for as long as you stay on the line. I stayed on long enough to write down the phone number. DO NOT press a button. All that does is let them know that they reached an active line, and they will continue to call even more. I have been an administrative assistant for more almost 20 years. I have learned little tricks like this!
