Membership Deduction without Permission

I cancelled my membership around July/August 2023 as I was moving house. A representative contacted me in May 2024, about a promotion that was being offered. I mentioned I will go look at the gym near to where I live and that I do currently have a gym membership with Planet Fitness which I will need to cancel if I decide to rejoin Virgin Active. I didnt visit the Virgin Active gym and I did not sign up a new gym membership. However, on 3 June 2024 Virgin Active deducted R1080 from my bank account. I have tried calling the center, a few times to resolve the matter, with no success. The call center staff were unhelpful, they all mentioned they are escalating the matter to a manager. Nothing has come of it. In my opinion this deduction from my bank account without my consent is *****.
