This number called our business today at 0848 hours, before we were even open.  I saw "Perth Amboy NJ" on the caller ID and knew there was a 99% chance it was yet another scam artist or unwanted spammer.  They did not leave a message.  A while later, I blocked my phone number and called it back.  Boiler room noise in the background so I knew my suspicion was right.  The guy who answered blathered something like "National Pin."  I asked what he said.  Slower, he said it was "National" and it was "Tim (something-or-other) speaking.  I asked why he called our office.  He tried to get my name.  I demurred and asked my question again.  He then told me they were a "full service brokerage office."  "Oh, so a scam artist or spammer," I snarled.  Then I offered a colorful suggestion about an activity they could do to themselves and slammed the phone down.  He was calling from a VoIP phone number.  Gee, why wouldn't I trust our money to a cold-calling "company" who doesn't even use a designated landline?  What could possibly go wrong with that situation?
