Extending contract term due to covid, blaming customers for lock down

I have signed a contract with them in 2019 October for a 24 month period. We were promised that the club will start opening at the end of March 2020. Due to lock down this did not happen, And the gym was only open December 2020 when the first debit order was taken. I was thinking that my contract will expire in October 2021 if there was no lockdown. When I contacted them to give notice in November to cancel my contract since I was now relocating, I was told that due to Lockdown, the contract was only activated in December, and therefore it will expire in November 2022. This information was never disclosed to me, I am now supposed to pay the cancellation fee, or keep on paying the gym i cannot attend. So I am wondering which steps I should take to address this matter, because I have brought this matter to their attention but they seem not to be bothered that they did not give notice about membership extension due to lockdown. They keep on sending debit orders to my account every month
