Cancelled membership

I have been a customer for over 8 years now, I received an email that my membership is now cancelled as i did not meet the required visits - i called the call centre and advised them that the reason i could not meet this was due to medical reasons, How can a medical aid say that they care about a customers health yet cancel a membership if the customers health prevented them from using the gym? i was physically unable to go to the gym.....You guys suck, IF this is not resolved i will go to the necessary channels (Media, Ombudsman, Consumer council etc) this is not how you treat loyall customers.!
