Keeps calling; left message today asking me to call "NSC"; no reason or identification given.

Caller left a message saying he was David Salinas and asked me to call NSC at a different number without any explanation or reason.  I have no idea who the caller or NSC is

David Salinas from New Bridge bank - said he wanted to talk to owner of company.  When pressed he said it was regarding a new business matter.  When pressed further said he is a banker, and wanted to discuss working with our office, etc.  Then said if he is busy, I can leave a voice mail.  Wasn't pushy, but didn't want to tell you why he was calling until pressed.  His number came from New York -646-589-829, but he asked to receive a return call on 401-525-8807.

Unsolicited call that seems like telemarketer at best.  I am on DO NOT CALL list, but these guys call anyway.

Received criptic VM from this number from Victor Napa of NSC who claimed to be in the same line of work as me but misidentified my line of work. Left a direct dial of 347-337-8223.
