I upgraded by subscription but now i'm paying double.

Hi, i recently upgraded my subscription to Creative Cloud because i needed Photoshop and InDesign, problem is, i am paying for Illustrator seperate, why? Does anyone know what i can do? I just want to pay for the Creative Cloud, why should i pay for Illustrator seperately if i literally upgraded to a plan that already has Ai? Any help is appreciated. I also have no idea how to reach Adobe customer service.
