How can I unverify an email once it is not being used?

Question

I changed my iTunes account email once. Now, I need to get back to that email, but Apple says it is being used in another account. I am pretty sure that the first email is not being used for any other account.
Through Apple's site, I chose "iForgot" to resend the password , so I should be able to login to that email account (if it was linked to another account, like they claim). Apple can't send an email for verification. Actually, they say that the email was sent, but it was not.
How can I unverify this email once Apple says it is linked to another account, but it is not (if it was, the iForgot email would come)?

Answer 1

for either method to work the state dividing lines must go past the state borders, for example, the line that divides these two states needs to go north a little bit more, I exaggerated the space so you can see, for your map this gap must be really small. Zoom in where you have trouble making separate shapes and fix it before using either tool.
