FIt24Gyms - Still deducting for cancelled memberships

I had cancelled my month to month gym membership with Fit24Gym in March before the lockdown and I am still being deducted almost R400 every month for the membership, I have email them, tried calling the Durban North, Umhlanga and PMB gyms and the lines have been disconnected, I have tried messaging on their social media which they are actively updating on however my messages are being ignored, I see there are a lot of clients with the same issue and this gym just does not respond, the sales consultants do not wish to give contact details of the manager or to assist as they are no longer working for the gym. This is very disturbing and if I do not get a response and a refund I will be laying charges of theft against them
