If you connected your VC account to an SNS account (Facebook, Twitter, renren, weibo) through the Support option in-game. You can transfer it to your new device by following the steps on Account Transfer.

If you did not, contact support through Support > Support tab, scroll to the bottom for Inquiries. Tell them that you lost your account and, when they ask, provide as much information about your old account as you can.
