I am really sorry about what you are passing through but this your issue is a complex case, have you tried to contact their support?
You can move your thread to this section
https://bitcointalk.org/index.php?board=129.0 if you do not receive good response from their support but make sure you have proofs that the account is actually yours.
Thank you for your attention.I am sorry I am new here,do not know well the rules.I try to suppot for more than 5 times,They just tell me to check me eamil,everytime the same answer.So I cmpained here.
I can prove I do have the account.I can tell them the account have which coin and the exactly total number,even I can prove the BTC transfer from which address.
I do not know how to move to another thread.so I just write a new topic.
