A couple months ago I signed up for a bundeled FIOS TV+Internet for ~90 bucks a month. For the first 3 months, Verizon gives you free preimium channels such as Showtime, HBO, Cinimax, etc. Will these channels be ended automatically after the 3 month period? If not, how do I unsubscribe from these channels so that I don't get billed for them in my 4th month. Many thanks if anybody has already gone thru this and can explain a solution to me.
