They have called me as well, and like other posters, I don't answer calls that aren't in my contacts. I called them from the landline at work and unsubscribed. Of course who knows what other crap this will generate, but you have to start somewhere.
Someone from this number calls at least once a day if not twice. No one says anything when I pick up the phone so I have let it ring for the last two days. They still continue to call.
