Sling TV review: Rewards

I have had sling for a few months now, when they started the rewards on sling, they specifically put in comments saying X amount of people will depending on how many entries there are. I or my wife have watched sling everyday and have never heard of anyone winning. My thoughts are that have decided to keep it in the family so no one else will win. But after months of seeing this and haven't even won a free month tells me all I need to know. Since it ends in 15 days and I haven't won even that will be enough to go ahead and cancel. They(sling) can keep it in the family and surrounding state of Pennsylvania.
