Purisaki Berberine Patch Subscription Charged Me Without Consent

I am writing regarding an order for the product “Berberine Patch” from Purisaki / Yide, which I bought through a Facebook advertisement around 30 March 2026. I did not sign up for any subscription, but since that time payments have been charged automatically from my Visa card issued by Bank Leumi, and by now approximately three payments have already been taken. I am a pensioner and I do not have the financial possibility to continue paying for these charges. I did not receive clear information that this purchase would create an ongoing subscription, and I was not provided with simple instructions on how to cancel it. I also do not know how or where to contact the company or seller to stop these payments. With this complaint, I kindly request that all future supplies, shipments and any further payments related to the Berberine Patch order be completely cancelled, and that I receive written confirmation that the subscription and all future charges have been stopped. I would be grateful for your prompt assistance in resolving this situation.
