Same thing happened to me today no card number stores or used in my Facebook account. There was 2 separate transactions charges.

Thanks for contacting Meta.

We've detected suspicious activity surrounding your card that resulted in purchases you didn't make. I've issued you a refund for those fraudulent purchases.

Your payment provider usually makes the refund available to you within 3-5 business days. If you still haven't received the money after 7-9 business days, I recommend contacting your payment provider for help getting your refund. Keep in mind that we won't be able to refund any overdraft or service fees you may receive.
