Received a call rang once called back it was an automated woman telling me I received an award for visiting a site and to press 1 to receive my $100 rebate card and press 2 to be removed from the list!
rang once then stopped. left no message. can confirm that mesha was right: i returned call and it was about a rewards program; press 1 for reward, press 2 to be placed on their do not call list.
