Unable to unlock Apple account
I have another Apple account (not this one) I have owned since 2010 that I am attempting to log into. When I try to log in I am told it has been locked for security reasons, and when I try to unlock the account I am told the phone number is incorrect. I have only had a single phone number my entire life, have never had to use that number before in the 15 years I've had that account, and the last 2 digits displayed match up to my current (and only) number. So either it was originally entered incorrectly or someone logged in to my account and changed it. I chatted with support and they told me the only way to do anything is with that number. So it seems I am now permanently locked out of my own account despite the fact I know the login info and still have access to the associated email account? Is there no alternative way to verify that I own my own account or send a password reset request to ensure security?
