Scammers & number harvesters. Calling this number back immediately plays the bullsh!t recording, "Press '9' to be put on our do not call list." That's about as believable as using a Fisher-Price telephone.
Scammers! They'll call to "update your Google search status" incessantly. Stay on the line to ask a question about who their company is and where they're located and they'll hang up immediately. Super cool.
