Called home then cell, but had the wrong name

Call from Rivera Casio.  Told them to place us on the do not call list.  This was an unsolicited call for a vacation offer.

Just received one of those calls but the line was dead when I answered.  Maybe the autodial didn't work properly.  This is the second call I've received in two days from different numbers.  this number was from Los Angeles.  The other was from Las Vegas.  Random dialing?
