Robo recording call regarding a get rich scheme. Hung up and put the number on by "block" list. When I called back, got msg. that this party has not set up a mailbox yet.
This is a 60 second recorded message telling you to push 1 to learn how you can put $10,000 into your bank account every week blah blah blah----finally at the very very end it lets you hit 9 to never hear from him again. I never should have heard from him AT ALL.
