I am unable to access my email account. Like many others . But will they help me?

I am unable to access my email account. Like many others on here I hvae tried to fill in the required form, but as I have a few email accounts, I have stopped sending emails from this account, I set this account jp pre 1999 so I have no clue what the secruity questions would be, ihave moved house so I do not know what postcode I would have selected, or changed it.I understand that secruity should be tight however that has to be someone I can talk to to prove I am the orignal owner! apart from filling in those forms for a computer to reject you!!!! Help!!!!
