I'll just add this one to the list -- heavily accented Indian male, insisting my boss said I could help with a survey about SaaS services. (He'd done some homework, though, because he got the name right.) When I asked him to send a message with the questions because I couldn't understand him, he insisted it would take only two minutes. I had to hang up. Since then, two calls a day, electronica happy music when I don't answer. Will send the voice messages straight to junk mail now.
exactly the same thing happening on my end. Heavey Indian accented male claiming to be from some company wanted information regarding my boss...I keep hanging up on him and telling him to stop calling..he lied and said this was the first time he called me i hung up on him.
