Minor Age Verification Fails

I have received an email to verify my child’s age, and from the very first try, it tells me the birthdate is incorrect and I’ve tried too many times, try again later. I need to contact someone to help reinstate his account. Where can I go to contact a support team to help me with this? I have been to the Meta Store and the AI bot kept giving irrelevant information and no option to send anyone a message. Please help.
