Gym Company makes it impossible to cancel if you are not in Johannesburg (Moved to Cape Town)

I moved to cape town last year September, I have been trying to cancel my gym membership but they won't allow me to.

According to Gym Company's twisted logic (Almost ********), I have to fly to Johannesburg to fill out a form so that I can cancel a membership I am not using, I have now reversed the debit orders, and I have put a stop payment on my account, you ignoring me for months have put me in this position, I will not pay a cancellation fee as you have debited me enough and I have requested to cancel, so take these F!#KING debit orders as your cancellation fee!!!
