This is a telemarketer from IPA (International Profit Associates). This "consulting firm" has a very shady reputation with high pressure sales tactics. They also go by IBA and other names.

A gentleman keeps calling us too.  He has not been rude, but very persistant in reaching our owner....claims to be calling from "corporate headquarters".   We are a small business and have only one location so we ARE corporate headquarters.  The things people will do!!

Called ID's himself as "Michael Adams" and goes as far as to start humming the theme music to "The Adams Family" show...
Reluctantly states he's calling from "Intergrated Business Solutions" however, turns out he' really calling from IPA - International Profit Solutions.  Some of his associates actually conducted a mtg w/ our company president several months ago - and they were basically told we weren't interested.  They continue to call - all you need to do is put them on hold, and they hang up within seconds.  Morons.
What a demoralizing job these people have.
