HARASSMENT FROM VIRGIN ACTIVE

I joined Virgin active Sandton CBD in January 2019 and in March i was still going to gym but then i found out that i was pregnant, i then froze my membership in June because i needed to consult with my Gynecologist if it was safe to continue working out because of my pregnancy history. my doctor said to hold of going to gym for the duration of my pregnancy because i am considered high risk. i then sent an e-mail with Dr.''s letter to virgin active on 15 July 2019, 10:51:06 requesting cancellation because it didn't make sense to keep the membership frozen when i wasn't gonna go for the duration of my membership as my estimated date of delivery is 02/12/2020. instead of cancelling my membership, i received an e-mail the virgin active wanted to provide me with more options a very rude woman buy the name of Marilyn told me that they were not going to cancel my membership and that they will freeze it and i will have to pay 50% of the membership while i'm not coming to gym. when i first joined the club i was tol that if cancellation is due to a medical condition and it is ordered by the Doctor then the cancellation fee is waived, i have a condition called PLACENTA PREVIA, meaning i cannot do any physical activities and then i'm forced to keep my gym membership, for what. i keep getting harassed by all these call center agents telling me that i need to pay for my membership. i do not have a membership anymore because i cancelled it. CAN YOU SORT THIS THING OUT ON YOUR OWN AND LEAVE ME ALONE, I REALLY DO NOT NEED THE STRESS. I'M NOT USING YOUR GYM OR ANY OF YOUR EQUIPMENT SO LEAVE ME ALONE.
