I had the same experience. One way to tell it was gonn be spam is that it took 10 seconds for the pre-recorded message to begin. If you ever say "Hello?" And it takes more than a second or two to respond, 99% chnace it's spam and in the rare event it's not if it's important they'll call you again.
Make $10,000 in 14 days and them make another $10,000 every 14 days after that. I just hung up. I make $10,000 every week, this would be a demotion. ;-)
