I got the error code 333000 everytime i try to open the ingame store, i have arround 1000 coins and i cant use them, a GM told me to open this topic because they dont know why this happen, i tried updating all my profile, billing address, etc. and nothing changes so here i am finding a solution from players instead the company who made the game and they dont know why
Good luck, going on 3 seasons of this issue with no effort on blizzards part to fix it.
