Transfer not possible but getting penalised for cancelling

I joined Planet Fitness Newtown around May 2017 and in December I got an opportunity to go work in Durban. I tried getting my membership transferred but found out that they DO NOT HAVE a branch in Durban, so I was forced to cancel. I have been charged over R1 000.00 in penalties for the cancelation, which I obviously cannot afford with the moving expenses and all. Being the honest person that I am, I went to the branch manager in Newtown and BEGGED him to motivate for them not to charge me but he REFUSED. He did not even want to try. So I am now expected to pay monthly subscriptions for a gym in Joburg while I'm in Durban and cannot go to gym since I cannot afford the penalty. This is not far on all levels as I cannot join gym this side and pay for two gyms so I'm stuck paying for a membership I don't need and will not be using. After supporting you for months, you treat me like trash.
