Yesterday I tried to buy with coins Legend of Dungeon but every time I try it this happens. I contacted with the help email but now there are few keys left and the issue is not solved yet so what can I do redeem it? It’s the second time this happens and I don’t want to end without the game though I have more than enough coins…
Your accont is a duplicate so u are ban from the coin shop…
We’re looking into this!
The game is already sold out so there’s no hurry…
No worries, if we find that it was an error on our end we’ll get you a key. 
Nice
