Lost data from game

by mistake through a link device I lost all data from the game. can anyone help me how to get them back. I am level 11 and co-leader.

Sorry man, your account is gone, its a shame but they dont have account backup, all you can do now is join heroic magic duel discord and ask for compensation in bugs-feedback channel, best of lucks.

No data backup. Sucks for money you spend and lose it all . I just bought a chest for quests and got chest and no quest who can fix this ?
