I’m having trouble accessing my previously linked hotmail account

Prior, I had three hotmail/live accounts linked together each with different passwords that I've forgotten over the years, except for the main account that I used to switch to the other two. I have tried using the form to recover the passwords to each account, however, neither secondary account had any sent emails, or any created folders, or billing info. So they did not have enough information to recover them. I've filled the form out three times now, each time I've gotten an email back saying that the automated system couldn't verify that I actually owned the account and that I should just abandon the account and create a new one. And as much as I'd like to do that, the secondary account has information that I need to access in the future. So... Help me, please? Q.Q
