Vista... something, it is a discount membership scam, they get you to say "yes" to sending a few vouchers, validate your credit card, then bill you $30 monthly for your "club membership"
These scammers are buying your info from someone you do business with and in many cases have the last 4 digits of your CC number.
Another annoying call to get money. When I said NO-NO-NO they completely ingnored it and continue with their message. We need to start a movement to have Congress make these annoying calls a crime. It is time to say enough is enough!
