Famradar.io Complaint About Unauthorized Charges - Need To Cancel

I live in the United States and I am being repeatedly charged 49.99 USD by a company called Famradar.io, a service I have never used or signed up for. These unauthorized card payments appear in my account history and, as far as I can see, they have been occurring since around February. Some payments were successful and some were declined due to insufficient funds, but all of them are completely unknown to me. I have tried to research Famradar.io, however I cannot even find a proper website or reliable information about this company, which makes the situation even more concerning. I have never knowingly registered, started a free trial, shared my card details with them, or given any form of consent to be charged. I contacted my bank in the USA multiple times and filed fraud disputes regarding at least three of these 49.99 USD transactions, but my claims were denied. Despite informing the bank that I do not recognize these charges and never authorized them, the withdrawals have continued or at least there have been repeated attempts. I request that all unauthorized charges made in the name of Famradar.io on my card be fully refunded, that any existing subscription or payment agreement linked to my card be cancelled immediately, and that all future payment attempts from this merchant be permanently blocked. I also ask for a written confirmation that the cancellation and blocking have been carried out, and an explanation of how these charges were allowed and why my fraud claim was rejected despite my clear lack of consent. I want this situation resolved urgently so that no further money is taken from my account for a service I have never used and cannot even properly identify.
