Got a reply from support:

We are working on restoring everyone's balances as we are collecting back overdrawn funds. All reimbursed funds will be distributed evenly between all effected user as those come in. We will also divert 33% revenue share to all accounts in order to speed time of balance recovery. Unfortunately we are unable to provide any more information for individual accounts, in short; your balance will be restored once we collect the missing funds for everyone.

Mr. Data - Technical Support

Let's wait and see seems like they are working on it

Same here! All XRPs gone from my wallet. I have emailed support to ask for an indication on when we can expect our XRPs to be restored, but no answer yet.
