Showtime,Cinemax,Starz

When i go to the comcast online order page for Showtime , Hbo ,Cinemax , Starz ,etc.  Only HBO is showing.  No Showtime , Cinemax , or Starz.  Does that mean they are no longer aviable in my area ?

I want to unscribe to Cinemax and Starz but they are not even listed anymore.  Looks like a lot of selections have been deleted from the lineup.

It is called the The add / manage premium content page
