So, after two months my problem is still not solved. Delisting delay did not change anything. This exchange seems to be completely out of service.
My guess is they didn't actually have the coins to distribute back to their users.
When people started requesting withdrawals, they forced KYC on them. For those who passed the KYC, they upped withdrawal fees. For those willing to pay higher withdrawal fees, they upped the "minimum" coins for withdrawal. For those who could withdrawal the minimum, they took wallets down for "repair".
What's weird is I just tried logging in using my account with them and it is now also locked. If I actually had coins on there I would find it quite unsettling.
