FULL STORY Questions: Whats gonna happen?

My 13 year old friend decided to put in a fake credit card number on a scam website and the website also required him to put an address and a phone number, he put in a fake address and a random credit card number that he typed, (he just smashed his keyboard numbers) and accidentally put in his own phone number and he received 2 text messages after that, “His credit card is limited “ and “his credit card was locked due to suspicious activity” now what’s gonna happen to him?
