No service, but they expect payment.. sickenning

I signed up during Covit. At the time working from home.. bellville was my closest branch. Then 2022 we had all to go back to the office. I called in trying to change my branch. But was told I must speak to sales guy. Who's number I no longer had. Then I reversed my Debits. Since they were making it so difficult. I was not Gona pay for a service I could not use... I reached out again. Saying I'm willing to extend the contract for the months that I have missed. As I would then go out of my 24 contract term, and they need to just tell me what I must do. But now I get calls from number collections. And the actual 24 months is over . So why are they still debiting. I had 9 months left of contract to pay. I will pay my 9 months.. subject to Zone fitness allowing me to benefit from my 9 month payment and not just ignore my requests to change gym branches. Please email me.. *** as I'm also in a call centre. And I'm not answering nimble, I have no dealings with them.
