Missing Season 5 AMC Fear TWD

I thought the show had ended at season 4 of Fear The Walking Dead. Eventually I searched for it on IMBD, low and beholdl!! I had missed an entire season. Everyone wanted the public to rent each episode foe a minimum of $1.99 SD or buy the season for $26.99 SD. Since I already pay for AMC I feel it would be counterproductive and unfair to pay for what I already have paid for.

Please rectify this situation.

Thank you in Advance,
