My boosters disappeared a few days ago and tried to contact support through the game with no satisfaction as the contact function does not work. I am very unhappy with these disappearances as it looks like you folks are trying to cheat the players. Most of these we won as awards by passing levels, some were purchased. This happened to me with Candy Crush and I stopped playing it. Please see that my boosters are returned to me or I will stop playing this game as well as never play another King game EVER!
