X3 Sports Won't let me out of contract due to medical condition! Atlanta, Georgia

I had surgery on both of my feet and my doctor wrote me a note stating that I can not work out for an indefinite period of time due to the healing process and other complications that could occur especially with participating in boxing. X3 - cancellation department and location - are trying to tell me that I can cancel my contract but only if I pay the full termination fee. I can not help the fact that I am not able to hold up my end of the bargain and every other gym I have researched would let you out due to having a medical condition that prevents you from using the facility, the ones I checked are snap, LA Fitness and Golds Gym, I am sure mostly every other gym allows this.  Also, I sent an email to X3 Sports on 1/10 and never once received a response back, I ended up having to go in there today to finally figure out what is going on - that's horrible customer service!
