Female caller from +84 4 9279136 spoke fine female English, wanted to speak to the person in charge of our Google Adwords account.  And then the person who handles our web site as clarification.  Said she was calling from Captain Marketing and that they were "partners" with Google.  When I pressed her on what that meant, she had no idea and could not explain the relationship.  When I told her that regardless I'd be reporting her violation to the Do Not Call List, she got abusive and in my face demanding to know whether it's a personal or business line and I told her I was not going to answer that.  More abuse and then she hung up.

Fascinating that it came from a Vietnam phone # - clearly a spoof on the caller ID, gee, I wonder why?  You guys really need to add a Call Type of SCAM.
