Cancellation struggle

I've been trying to cancel my membership with virgin active as per the contract i was advised its a 1 year contract of which i took in September 2021 and when i called in August to inform that i do not wish to continue due to affordability they advised that it will be cancelled in November. How is it a contract that started in September the previous year be terminated in November. The service level in astonishing and disgusting because now i feel like im forced to pay for a contract i do need anymore. I feel ****** and ****med.
