Membership fee increase due to pregnancy

I am currently 37 weeks pregnant and was unable to attend gym for the last 3 months as instructed by my gyne. Reason being due to complications which could be detrimental to my health as well as my unborn child. I have booked my bed through discovery in August 2014 which makes discovery fully aware of my pregnancy, however I was still required to swipe my gym to achieve 36 visits within a 12 month period. I did this to a point were i was not able to drive myself to the gym or get into a car any longer due to minimum mobility. I eventually asked my husband who frequents the gym to swipe my card as I am unable to go myself. On a few occasions the gym staff would do it for him after explaining the situation until one day when one of the staff members put a stop to this explaining that it was ***** because I was not present. All well and good however I was not able to be present due to my pregnancy. Discovery vitality is quick to talk about living a healthier life however do they really care about their clients health? I fairly doubt this if they not willing to assist or consider pregnant woman. LADIES BEWARE OF THIS INCONSIDERATE COMPANY. DO WE PAY VITALITY TO BE TREATED LIKE THIS?
