Mistakenly sent coins to Undermaintanace Wallet

[btccrusher]

How stupid am I! I didn't notice that the wallet has a notice "Wallet status: Maintenance" in Yobit exchange. As the title says, I sent some coins three days ago. The wallet status is still - Maintenance and the coin balance is ZERO. In explorer, my transaction is OK. Am I lost all those coins? Or I may get them once the wallet status changes to OK.
