They called but left no message. Called the number back and got a recording that I was selected to receive a rewards rebate card good at "many stores" just for visitng one of their web sites (who knows, I visit dozens daily). Then to either press 1 to receive the $100 rebate card or 2 to be placed on the do not call list (I thought there already was a national do not call list?). They called themselves Rewards Redemption. The number is reported to be based out of Ventura, California, by Spokeo.com
