Unauthorized FamRadar Charge on Navy Federal

Today, a charge of $49.99 from Famradar appeared on my Navy Federal account, even though I have never signed up for any Famradar service, subscription, or knowingly shared my card details with them. I do not recognize this transaction and I consider it unauthorized. I request that any existing Famradar subscription or billing agreement linked to my Navy Federal card be immediately blocked and cancelled, and that Famradar be prevented from charging my card again in the future. I also want this unauthorized transaction to be investigated and handled as a security concern, since I have not given consent for this payment. I expect clear confirmation that Famradar has been blocked from my card and that no further charges will be processed.
