I called it back from my office phone and it said that I recently visited one of their websites and qualify for a $100 rebate gift card. I pressed the number to talk to someone and I asked how I would have earned it. He said I am a frequent shopper at some retail store.
I didn't give him my name and instead I said THANK YOU and hung up. I don't know if it is legit or not, but like my daddy always told me - if it sounds too good to be true, it probably is!
