Nightmare Cancellation

I signed up at Ignite Fitness branch in Randburg but I then cancelled this membership the next day because I realised that the gym did not have the spinning classes I needed at a certain time. I was assured that the cancellation would gp smoothly but it has been a nightmare ever since. It's been more than a month now and I have not yet been refunded my joining fee. I have to call the gym everyday and I am being told that the matter has been escalated but nothing in happening. To be honest, I regret ever going to this gym.
