Forgotten Password and existing AppleID email address doesn't exist anymore

[iMore Question]

The email address was used for my AppleID doesn't exist anymore. Then I also have forgotten my password, so it makes it quite impossible to access my account to change my email address and AppleID.
I have tried various options but to no avail.
