Pathetic service

I have been with the gym Company for atleast 3 years now, if not more. I have placed a cancellation on 25 September 2024 via email, to their info email, support and the manager of the gym I go too, mind you... Cancellation was also sent through on the Facebook portal. I was told to contact the gym manager Trevor to confirm cancelation of which I attempted 3 times but the receptionist would jusy route me to Trevor who didn't answer on all 3 attempts. I would like to know what is the process and procedure that the gym Company follows as this is clearly no great service! I want my subscription canceled ASAP and I would appreciate confirmation of this!
