JustDone AI Unauthorized Charge After Seven Day Plan Subscription

I am writing regarding an unauthorized charge of $20 made today, approximately one hour ago, by Justdone AI to my card ending in 0933. I had only signed up for a 7‑day plan, which is why I am very confused and concerned about being charged this additional amount without my consent, knowledge, or any clear explanation. I am located in The Bahamas and was using Justdone AI under the impression that I would only be covered by the 7‑day plan I selected. At no point do I recall approving a further $20 payment or any recurring subscription related to this service. I kindly request that this $20 charge be fully refunded to my card and that any unintended or hidden subscription associated with my account be cancelled so that no further charges are made. I expect a prompt clarification of why this charge occurred and a swift refund of the amount taken without my clear consent.
