Have you tried withdrawing your fund and does not experience any delay? I think there is no issue on the display of the balance but rather the crediting of the deposit and processing of withdrawal.
Yesterday I made a deposit and withdrawal. I waited around 4 hours for my deposit to be recorded in the site balance and waited around 5 hours for the withdrawal to reach my wallet. It may be annoying but as long as they are committed to fixing it, it's certainly no problem and I'll be back in a few days when everything is back to normal.
