Contracts signed under false information, they only care about commission and lie to clients just to have business going

Greetings. Some time last year I was recruited to join the gym. I informed the lady that I am on my gap year but the following year, which is 2024 I am leaving the province and going to another province in order to further my studies. The lady at the Randfontein branch, Tambotie mall assured me that I can cancel anytime when I wanted to To my surprise when I sent my cancelation request, I was told to pay an amount of R800. When I asked the manager in Dec last year doe the call recordings of that conversation, till to date. I have been sent from pillar to post without any success. The recruiter has now been moved to another branch unknown to me The manager since promised to get back to me but hasn't.
