Now that I need to use one of those I tried the security question and even though I'm using the right answer I get an error saying "the wrong info was entered too many times. try another option, or try again later." But I have tried after a few days and I'm still getting the same error.

I think there has to be a record of which account was linked to another, if the accounts were linked then it means you are the owner of all, can I just have access back to my linked accounts this way?

I haven't used them in quite some time so I cannot fill the recovery form enough to get it validated, even when I have some details which no other person could know.

Let me know if there is a way I can get them back using some other method than the standard(security question, alternative email address, recovery form)
