Recovering account w parental email

Hi, I’m trying to recover an old account but I’m not sure when I last logged in. When I search for the account, I can still find it and visit the den, but when I try to reset the password, it says an email has been sent to parental email. However, I never actually receive the email. Is there anything I can do while waiting for a response? I’ve already submitted a request, but it’ll probably take a while to hear back. Do you know how long it might take?
