caller stated he got my number at a business meeting a few months ago. He said he ran into someone who claimed i was ambitious and wanted to know if i was interested in making money on the side. i asked again where he got my cell number and he gave a vague response. when i asked if this was an Amway / Quixtar call he ended it quickly.

This guy will never stop. Salesman for some "training". No matter how much you tell him you're not interested... he will call and call again. If you have the ability, send him a letter to cease and desist.
