Reset Password

So it does seem that you have forgotten your password and are trying to reset it

Apple Support cannot send you a password reset link.

For this issue you need to attempt to reset the password on a trusted device first.

Settings > name > password and security > change password

You can follow this > https://support.apple.com/en-us/HT201487 " If you forgot your Apple ID password "

You can follow this > https://support.apple.com/en-us/HT204921 "How to use account recovery when you can’t reset your Apple ID password"

If none of those options work for you, then I would attempt to do account recovery at iforgot.apple.com as stated in that resource above.

Please note that Apple cannot speed the account recovery process up.

I hope this helps ;)
