Sea World Parks Busch Gardens annual pass forever contract Orlando Florida

I purchased an annual pass which should have been called a subscription pass. No where except in the fine print is this mentioned.
I purchased SeaWorld annual passes for my husband and myself early last year. Since I do not have a lot of money, I chose to use the EZ Pay method, which charged 12 even payments to my credit card. The passes were specifically called one year annual passes. There was nothing clearly advertised up front about this being a subscription and having to cancel the pass. After all, it said it was for a year! Since I agreed to a year commitment, when I read the terms, I misread the part that my credit card would be charged AFTER the year ended. And of course there was no contact to remind me that the year was going to end and I would need to cancel, despite getting lots of emails from SeaWorld. Again, this still doesn't make sense to mecancel my one year pass after it is over? My concern is the lack of good business practices in making it clear up front and center that the EZ Pay would be a subscription.
