Unsubby Attempted An Unauthorized Subscription Payment, Request To Cancel

I recently noticed that an attempt was made to charge £10.95 from my Revolut account by Unscubby / unsubby.com as a subscription payment. This indicates that there is an active subscription or recurring payment attempt in my name. In the past I registered for an Unscubby service, but I did not clearly agree to any ongoing paid subscription and I do not wish to continue using your services. When I contacted support, I was told that I have to cancel the subscription myself, which I find unsatisfactory because I did not knowingly authorize these recurring charges. I request that you immediately cancel any subscription or recurring payment linked to my details, confirm in writing that no further payment attempts will be made to my Revolut card, and ensure that no future charges are taken or attempted without my explicit consent. If there are any other pending or hidden subscriptions under my name, I also ask that these be terminated and that my account be fully closed.
