Someone else is trying to use my email address
I started getting email notifications today that I need to click on a link to verify my appleID. However, the email associated with the new account belongs to me, but isn't part of my account. It wants a phone number ending in xxx62. I don't have anyone in my family that uses a phone number ending in 62. How do I get this resolved, and the email address removed from the other persons account. They have even registered their iPhone8 against the account.
