Just got called by this number while I was on the phone. Rang twice and no message left.
Called back to a voice message saying "Hi! This is Lisa from Reward Redemption. We called you because you recently visited one of our affiliated websites. And in appreciation, we have a 100 dollar rebate card for you - redeemable at popular stores like Walmart, Best Buy, Home Depot and many more!
