I have not received an email to confirm unlock request

Hello, I have submitted a request to unlock an old iPhone 7, however, I have not received an email to confirm the unlock status. The status of the request shows following "

It looks like you haven't confirmed so we hit pause on your unlock request. Use the link in the email we sent you and we'll get back to business.

Can't find the email? Check your spam folder"

It is not in the spam folder and it is now over 24 hours since I submitted the unlock request
