4Rabet — Withdrawal request is not processing

I am 4rabet user from past 3 years but never happened to me like this. But my withdrawal request is not processing from past three days.
I put a mail to them and they replied to submit kyc documents and I submitted. I submitted lots of withdrawal in last three years but never asked like this. But now why they are asking so please solve my problem as soon as possible
Almost 60k stucked in my 4rabet account.
