Caller with New York accent asks for business owner by first name.  When asked if he'd like to leave a message, he wouldn't provide name of business calling from, just that he'd call back later.  You can hear other call center type calls going on in the background.

This person is calling a business line and will not idientify himself. Hangs up when you begin asing questions. Starts off by calling you by your first name.

National Securities. They called for the retired CEO to speak to him, would not tell me why and getting information from him was like pulling teeth. Sounded like a boiler room behind him (a loud call center).

Repetitive to the point they made themselves nuisance calls within 30 minutes. (6 so far all showing the same CID)
Barely civil call center representatives (plenty of background call center chatter going on behind them) first requested someone who passed away over 10 years ago. Now the repetitive repercussion calls are asking for people who don't exist in my directory and when asked what the purpose of -their- call is, they either hang up, hang up with an insult and only one of them said thank you but not in a way that made you feel all rosy and fuzzy inside.
