Foreign accent.  Insists he's from geek squad and must talk to me about my pc.  When I tell him I've never bought from them and they have no reason to call he gets offended and insists I'm wrong.  Told him I'm on the DNC and what he's doing is illegal and liable for harassment charges since he has no permission to call and he got offended and hung up.   This isn't the first time he's called and probably won't be the last.
