Bad service- gym contract

I had a gym contract with metro gym pre covid. In April 2020 I received an email stating that contracts will be stopped and no further deductions will be taken. Later that year I received another email asking me To follow the link if I would like to reinstate my membership. I didn’t follow the link as I didn’t want to make use of the gym due to high covid cases. 2 unauthorized debits went off and I cancelled them as according to the email, I didn’t have a membership. When I went back in 2021 to start a new membership I was told I owe for the months during lockdown. When I showed the guy at the desk the emails received he rudely dismissed me and told me I needed to pay. I asked him to show me where this policy was as the emails received were clear and I had not received any further emails outlining Ts and Cs due to Covid. I’m so disappointed in the way I was treated I ended up leaving as the guy told me off and just gave me some email address that can be used for customer complaints.
