Well, did you already contact their support about this? They probably can help you with account verification.
Only support can really solve this out to give him another options to resolve the problem.
Yeah like what I've been doing for a long time before I make a transaction in an exchange I'd made sure that I already know what should be done and checking the withdrawal verification is a must look for me.
I wonder why OP chose that btctrade.im which in the first place, not a popular nor trusted site.
I would suggest to seek help to your local board and know if they'll help you. Hopefully, someone more knowledgeable will notice this thread and help you out.
Too bad you learned a lesson in a hard and expensive way.
