A man identifying himself as "David Cole" called our business asking for the Owner who died 3 years ago!  He was very pushy, slow to identify himself, would not give the name of his place of business and was otherwise rude, unprofessional, and bordering on FCC regulations.  If you see this number on your Caller ID, don't pick up and BEWARE.  Clearly this number is coming from a phony or fake organization.

Very slippery sales approach. Never did identify what they are pushing.
Very obnoxius

Calling to try to set up a one on one meeting for "services" which they cannot specify over the phone. Acting as "consultants" to expand your business. Very vague and want to set up a meeting right away. Trying to sell you services.

A man who identified himself as Donny called and asked for my boss.  He was very unprofessional, rude, and did this “street talking” on the phone.  When I asked for the purpose of the call, he said “uhhh, you guys do ehhh, business hah?”  I asked him if it was a sales call, and he shouted at me “Oh, I was gonna be your customer.  Ohh it’s all right”, then hung up the phone on me.  
Are there any way of regulating those Freudian sales calls?  I get these kind of “ghetto” phone calls at my professional business often.  The other one I had recently is from “Denise” at Nation Wide Compliances, who gave wrong phone number to call back, and also spoke with the ghetto accent.  After we report these calls, what are the things actually done to regulate them?

Just received a call from "Nancy," who, like the other posts indicate, was very unprofessional and vague about the nature of the call.  She kept asking questions and was random about the topic.  Highly unusual and irritating.
