Refund For Unauthorized Hint Charge

I am writing regarding an unauthorized charge on my TD debit card that appeared on my account on 04/26/2026 at 2:01 a.m. for $44.99 from “HINTAPP.COM/CA_V.” I live in Ontario, Canada, and I have never used, visited, or even heard of this merchant or service before seeing this transaction on my statement. I received a fraud alert text message from TD about this transaction, which confirmed to me that it was suspicious, but I have not spoken with a representative yet. The last four digits of the card used for this transaction are 2439. I did not authorize this payment in any way, I have not signed up for any trial or subscription related to this name, and no one else has permission to use my card. I request that this $44.99 charge be treated as an unauthorized/fraudulent transaction, that the amount be fully refunded to my account, and that my card be checked and protected against any further charges from this merchant or similar suspicious transactions. I also kindly request an investigation into how this payment was processed without my authorization.
