Is the original ticket still open? Did you send more than one ticket? If the original ticket is still open, you can just add to it and ask them how to verify your identity so they can assist you. If they don’t have another problem with your account or something you’ve done they can instruct you on how to send identification to them.
If you created just one ticket and it’s closed, perhaps they sent you instructions and you somehow missed that opportunity. If so and you have no other open tickets, you can open a new one. If you created multiple tickets on this situation or if you broke some other rules, they may not consider your account in good standing. I don’t really know how to advise you in that case, but you could try and contact them again.
