Jacquie et Michel subscription issue contact

Hello, here are the facts: unfortunately, I was tricked into subscribing to Jacquie et Michel Contact and paid €49.94 using Virtualis, a system that allows the creation of virtual, one-time-use cards. My question is as follows: how do we cancel their subscription and renewal, and can they continue to charge me even though the bank details entered are no longer valid since they were for one-time use? I received payment confirmation, so my card has been deleted. I only have the invoice number, the amount, and the billing email left. I'm really panicking and am currently drafting an email requesting my cancellation and subscription termination. So if you could advise me, please, it's really urgent.
