If you fail from everywhere, then at the last you may go for http://walletrecoveryservices.com/, ran by Dave. I have never tried such service personally but he got a good reputation[1] and good recent reviews on trustpilot[2]. He may help you if he is active. Since your pass length is too big, it may take a while but you should give it a try.
