Lost access to purchased episodes due to Apple's TV show restructuring

I purchased the t v show. i purchased every season. the final season, the final 2 episodes were each mini movies at one hour and a half each. for the twenty fifth anniversary of the show's, launching apple removed the final 2 episodes and listed them as the fifth season.. there are only four seasons, and I was able to previously access these two episodes, which are episodes, eighty nine and ninety. now, this t v show that I spent over ninety dollars in total purchasing in two thousand and five.I am told I have to spend an additional fifteen dollars plus tax to purchase the entire set again.Just to have these two missing episodes back. what can I do? how can I get help to make the situation right? i spoke to an advisor and senior advisor. they offered me a free movie rental. Which doesn't allow me to view these two missing episodes, and doesn't allow me to even watch them. the only option is to purchase them as part of the entire set that I already own again. i feel like this is extortion.Does anybody have any advice?
