Account Hacked need to regain access but the automated support is useless

My supercell account was hacked and they changed the email. Ive had this account for 10 years. Ive contacted the "support through the game multiple times and entered all the information they asked but was givin the response of :
"Unfortunately, we cannot proceed with
your recovery as we were unable to verify
that you are the original owner of this ac-
count.
