I really have steered away from firepay.
Info@firepay.com ,Be ready to scan your drivers license and bank statement (hopefully you have the same registered bank, if not there is still hope). You have the same email still correct? Why do you no longer have access to your firepay? Just keep hounding their support till you get a response.
If you do get your firepay cash back, deposit it into partypoker. They can only accept firepay deposits, but cashouts must be done by igm or Neteller.
