******* debiting of my account

Planet Fitness debited my account for over two years without notifying me that the membership had ended and would be renewed automatically. When I realized that I was being charged I called planet fitness and after about two weeks they came back to me to say that although they admit that they never notified me of the expiration of my membership and the automatic renewal (in contravention of the Consumer Protection Act and the terms of my contract) I had used the gym two months after the membership expired. But how was I meant to know that my membership had expired and what about the two years after that when I didn't use the gym and they continued to debit my account?
