Zone Fitness Contract -Good-luck trying to cancel your membership

I have been trying cancell the Zone Fitness contract since July 2021. The staff at Kloof Street advise me to email the request to their branch sales manager (*** ) and I got no response to my email sent 20/07/2021. Sales consultant advised when we signed up that we can cancell at any stage which is clearly false info as this is still ongoin. Zonefitness still debited me the 50% of premium even when gyms were closed and after my request to cancel. I eventually had to place a stop-payment to avoid additional unauthorised debits from my account. I had to call into Zone head-office to find out wa handed over for non-payment and I must make arrangements to pay balance. Also no email or SMS communication was sent to my primary cell and email which was the detail I gave to Zone when I signed up. After calling head-office they advised that account was suspended in November 2020 and handed over to Debt Collectin Agents (Nimble) but I only received 1st email from Nimble yesterday from below automated email ***. How is it possible that that it takes a year to try to cancel a gym contract that we were advised can be cancelled at any time.
