MEDICAL UNFIT TO GYM

I have been to the gym once, I signed up obviously to get fit, however I had difficulty breathing so I could not continue, later on the doctor asked me how do I feel when I run or exercise so I told them, they discovered I have a hytus hernia, which means some of my stomach is in my chest, Hence it applies pressure to my organs hence difficulty breathing etc, I called the called center to cancel my membership as its not possible until I get better to gym as I have been paying all these months for something I have not used, they said it wont be possible and I would need to pay more than R2000 for something I have been paying every month for thus far. I can barely afford to the camera I have to swallow now this, disappointing!!!! I will tell all my friends on facebook, and twitter etc
