If you are a Premium member, contact Live Chat.  Otherwise, submit a support case.  You will probably be asked to provide some form of official documentation ( a driver's license or a passport, perhaps) to prove that you are the account holder.

If you reported to Linden Lab that your accounts were "hacked" (unlikely), they will have locked them automatically while they investigate.  That may take a few days, so be patient.

a slong your ccounts are on hold you can not get it back, also not with security questions.

If they are on hold and LL asks for the information and you can't give it you will never get it re-opened

Not remembering such important info is a sign for them you are not the owner.
