That was a mistake to say, "Yes." Now they have YOUR voice as a recording saying "Yes" and they can use it to enroll you in any program or product they choose, because, after all, you said "Yes" to some question that they will say you responded to. Not the question they actually asked you. It is the latest of scams out there. Their only purpose is to get you to say "Yes." so they can record your voice. At this point, I would watch your bank account and credit card accounts closely for a few months to see if anything weird pops up that you did not purchase. They may already have more information about you than you think.
