I believe this is a debt collector - the person that used to have my home number was apparently in the hole and now all I get all calls for her...Waited on the line, told them for the 4th time it was the wrong number and she said okay and hung up. Unable to call the number back.
Called with an automated message asking for Rosalie Gonzalez. Chose the option that "that person doesn't exist at this number" and it kicked me over to an operator. Told the guy that she doesn't live here and he said ok and hung up. Wasn't rude or anything.
It may be a collector, but I think it's a professional harassment system. They will keep calling until you get your credit in order, or they may just keep on doing it to trick people into paying bills they do not owe.
