Debit order after contract termination

I personally enjoyed my time at the gym and a very affordable price. The contract I took was 3 years (if I remember correctly) and unfortunately I had to relocate to another province. I paid the mandatory cancellation fee on August 5 2024 and I have the slip. Got told that the last debit order will go through on the August 25 and I had no problem with that. Boom September 25 another debit order and contacted the gym on two numbers; I got a response on the other one " Although you signed the form In August ,the 30Days notice still needs to considered. Bodyflo Management" After that I was never entertained. It's a good gym but the trend you will see are people being debited even after terminating the contract.
