Is AMC+ Free effective 8/16/22 a scam??

I have not been able to access AMC+ FREE streaming via the Icon, which appeared via my On Demand Menu last Sunday.. as effective 8/16/22 thru Aug 22nd. I just spoke with Comcast, who appeared to be completely unaware of this offer. They provided a ph nbr (for AMC). But, that number ([Edited: "Personal Information"]) only reaches a vm message for AMC.. which says the mailbox is full. [Edited: "Inflammatory"] The AMC series all displayed under my FREE column. But, once I select any show, it says "subscription needed".
