Starz Encore Thanksgiving promotion

When you send me an email telling me I can get these channels free during the promotion, I understand you are looking to entice me to keep them (as a paid service) ---- so if you know my name and my email, why don't you tell me EXACTLY which channels are free (obviously you know my zip code too)?!  

Well, since I didn't know the channel numbers, just went to OnDemand instead,,, and after exactly 15 minutes of the movie I selected, it said "Your movie is complete."  

An experience like this makes me never trust  your promotions again, I do not have time for this but I actually tried letting it play in the background. I will certainly never *pay* for such lousy service.  Big Fail, COX.
