I've looked around but haven't been able to find the answer I'm looking for. Apologies if I missed it while searching. My 3months of free HBO, Starz, Cinemax, and Showtime is up on May 14th. If I drop/change my premium subscriptions tomorrow (april 28th), will I keep them until my next billing cycle starts, or will they immediately disappear from my programming? And how close can I get to the May 14th deadline before I'm charged for the next month? Thanks!
