Unauthorised deposit using credit card

I do deposit my fund through credit card, but here's come a question, credit card fund deducted without the OTP. While I received a notice that my card get charged 104.49 USD few days later after deposit which I do not done that. Beware entering your credit card detail to Etoro, you might be a potential victim. I have raised the issue to Etoro hope can get a feedback from them.
