Advertising "FREE" Lifetime Movie Network preview...but not free..."SORRY"

My On Demand has the LMN advertising a free preview week from 11/29-12/5. Only gives me the option to subscribe to watch, so I requested a call back from company. Rep did everything she could as far as reset, etc. Then apologizes & tells me that she has exhausted all she can do. Says, "Although it says free preview for those dates, that I will just have to subscribe if I want to watch those movies. There is nothing more the company can do."  Why do false advertising on my actual account? Wish I could show a pic. Anyone else have this offered on their On Demand? Is it working?
