Same experience as Lorna - called back and had the option of pressing 1 for a vague, nonspecific gift card from a vague, non-specific site, or press 2 to be placed on do not call list. Pressed 2. Hope it works.
Received call on my cell phone, no message. Called number back from a blanked out phone, robo message says, "this is Lisa, you recently visited one of our websites and are eligible for $100...., press 1."
person who answered said this was "Family Savings Club," and when I wouldn't give name, he hung up on me.
