Unauthorized Charges by Facebook

Facebook has repeatedly made unauthorized transactions, without my knowledge or consent, using my registered credit card under the name of Facebook Ads. I demand an immediate explanation regarding the purpose of these unauthorized transactions and request a refund for the amount withdrawn. Moreover, I want to know how Facebook accessed my card information. I need answers regarding this matter as well. In addition, several other companies have also withdrawn a total of over $110 from my credit card. I am not responsible for paying this amount, as the bank allowed these transactions to take place without sending any confirmation code or seeking my approval. I am concerned about how such actions can occur without any notification from the bank.
