I'm in a similar situation, not on the Panxora CEX itself but on a ICO dashboard they've created in 2017.
As per the instructions try to contact
this guy here or send an email, he is still active and has recently launched a bounty program.
My direct email address is marcie.terman@panxora.io and anyone who is a client is welcome to email me directly if the rest of the team is slow to respond. I will try to help, though I am not directly involved in the settlements process.
Stay safe.
I hope this helps
